Dennis Wilson

He later contributed original material to their catalog, including "Forever" (1970), his best-known song. Wilson drummed on many of the group's hits, belying the popular misconception that he was usually replaced on record by studio musicians. He originally had few lead vocals on the band's songs, but his prominence as a singer and songwriter increased following their 1968 album Friends. Wilson, alongside Gregg Jakobson and Terry Melcher, was also embroiled with Charles Manson and his commune, a months-long association that ended after the Beach Boys released "Never Learn Not to Love" (1968), an uncredited Manson song revised by Wilson. In the early 1970s, Wilson recorded an unfinished album with Daryl Dragon, later released on the 2021 compilation Feel Flows, and co-starred in the 1971 film Two-Lane Blacktop, his only acting role. He is sometimes cited as an uncredited writer on "You Are So Beautiful", a 1974 hit for Joe Cocker frequently performed by Wilson in concert. His only solo album issued in his lifetime, Pacific Ocean Blue (1977), was released to warm reviews and sales matching those of contemporaneous Beach Boys albums, and has subsequently gained a cult following over time. Sessions for a second solo album, Bambu, disintegrated before his death from drowning in 1983 at age 39. In 1988, he was posthumously inducted into the Rock and Roll Hall of Fame as a member of the Beach Boys.

• Illustration — Wilson's Hawthorne High School yearbook portrait, 1961 Dennis Carl Wilson was born on December 4, 1944, as the second child of Audree Neva (née Korthof) and Murry Gage Wilson. He spent his formative years with his brothers Brian and Carl and their parents in Hawthorne, California. Dennis's role in the family dynamic, which he himself acknowledged, was that of the black sheep. According to neighborhood friend David Marks, Dennis's "raucous behavior" inspired other kids to nickname him "Dennis the Menace". Out of the three Wilson brothers, Dennis was often the target of physical punishment by his father, experiencing some of the harshest treatment. In 1976, he acknowledged, "We had a shitty childhood... my dad was a tyrant. He used to wale on us, physically beat the crap out of us. I don't know kids who got it like we did." Possessed with an abundance of physical energy and a combative nature, Dennis often refused to participate in family singalongs, and likewise avoided vocalizing on the early recordings that Brian made on a portable tape recorder. Dennis later described Brian as a "freak" who would "stay in his room all day listening to records rather than playing baseball. If you could get me to sing a song, yeah, I'd get into it. But I'd much rather play doctor with the girl next door or muck around with cars." However, Dennis would sing with his brothers late at night in their shared bedroom, a song Brian later recalled as "our special one we'd sing", titled "Come Down, Come Down from the Ivory Tower". Brian said of the late night brotherly three-part harmonies, "We developed a little blend which aided us when we started to get into the Beach Boys stuff." Dennis noted of himself, "If my dad hadn't given me a BB gun when I was nine years old, my life would have been completely different. With that gun I had something I could take my anger out on. Hunting, fishing, racing have been my preoccupations ever since." Brian told Melody Maker in 1966, "Dennis had to keep moving all the time. If you wanted him to sit still for one second, he's yelling and screaming and ranting and raving. He's the most messed-up person I know." Around the time he was 14, Dennis began playing piano and learned to play boogie-woogie styles. He remembered attending church gatherings with the rest of his family "because there was this outasight chick there... [and] I used to try and play boogie woogie on the church piano on Friday nights when all the kids went there to play volleyball."

• Illustration — Dennis performing on drums with the Beach Boys, December 1964 The Wilsons' mother, Audree, forced Brian to include Dennis in the original lineup of the Beach Boys. In 1960, Dennis began taking drum lessons at Hawthorne High School. Teacher Fred Morgan later said that Dennis had been "a beater, not a drummer" and "a fast learner when he wanted to learn." According to Brian, "We kind of developed into a group sort of through the wishes of Dennis. He said that... the kids at school knew I was musical because I had done some singing for assemblies and so on." Recalling their first group rehearsals, Dennis said that he was initially "going to play bass, and then I decided to play drums.... Drums seemed to be more exciting. I could always play bass if I wanted to." Brian would ultimately play bass. Dennis played the drums on their first studio album "Surfin' Safari" and sang vocals. The Beach Boys officially formed in late 1961, with Murry taking over as manager, and had a local hit with their debut record "Surfin'", a song that Brian wrote at Dennis's urging. Dennis recalled, "We got so excited... I ran down the street screaming, 'Listen, we're on the radio!' It was really funky. That started it, the minute you're on the radio." Though the Beach Boys developed their image based on the California surfing culture, Dennis was the only actual surfer in the band. Carl supported, "Dennis was the only one who could really surf. We all tried, even Brian, but we were terrible. We just wanted to have a good time and play music." In early 1963, Dennis teamed with Brian's collaborator Gary Usher. Calling themselves the Four Speeds, they released the single "RPM" backed with "My Stingray". In March 1964, Dennis moved out of the Wilson family home and took residence at an address in Hollywood. In the sleeve notes of the band's July 1964 album All Summer Long, Dennis wrote, "They say I live a fast life. Maybe I just like a fast life. I wouldn't give it up for anything in the world. It won't last forever, either. But the memories will." In December, Murry told a reporter that Dennis had been "a little too generous" with money and "cried when he learned about how much he had wasted.... Where the other boys invested or saved their money, Dennis spent $94,000. He spent $25,000 on a home but the rest just went. Dennis [is] like that: he picks up the tab wherever he goes." In January 1965, Brian declared to his bandmates that he would no longer tour with the group for the foreseeable future. He later said that Dennis was so devastated by the news that his immediate reaction was to pick up "a big ashtray and told some people to get out of there or he'd hit them on the head with it. He kind of blew it." Photographer Ed Roach, a close friend of Dennis, stated that Brian was deterred from the stage due to jealousy over the adulation Dennis received from the audience. Brian remembered that the attention Dennis received was "hard to handle". The girls would be going 'Dennis, Dennis' and run right past us to get to him." Dennis later said of his brother, "Brian Wilson is the Beach Boys. He is the band. We're his fucking messengers. He is all of it. Period. We're nothing. He's everything."

Brian wrote that he had felt that Dennis "never really had a chance to sing very much", and so he gave him more leads on their March 1965 album The Beach Boys Today!. Dennis sang "Do You Wanna Dance?" and "In the Back of My Mind". The former became the first song with a Dennis lead that was issued as an A-sided single, peaking at No. 12 on the Billboard Hot 100. Journalist Peter Doggett later said that Dennis' performance on the latter song "showed for the first time an awareness that his voice could be a blunt emotional instrument.... his erratic croon cut straight to the heart, with an urgency that his more precise brothers could never have matched." Released in July, Summer Days (And Summer Nights!!) contained Dennis's favorite song by Brian, "Let Him Run Wild". By 1966, Dennis had begun using LSD. His drumming contributions on Pet Sounds (1966) were limited to the track "That's Not Me". Carl said, "Brian liked to use [session drummer] [[Hal Blaine|Hal [Blaine]]] because he was so much more reliable than Dennis, but whenever Dennis got the chance to play he always did a great job. He played drums on more of our records than most people realize. I think because he didn't play on Pet Sounds everybody assumes he never played at all, and that's just not the case." During the Smile sessions, Dennis played on "Vega-Tables", "Holidays", and "Good Vibrations". It is rumored that the album's working title, Dumb Angel, referred to Dennis himself. Van Dyke Parks, the project's lyricist, credited Wilson with inspiring the name of the would-be album track "Surf's Up". Dennis said that the group ultimately scrapped Smile because they became "very paranoid about the possibility of losing our public.... Drugs played a great role in our evolution but as a result we were frightened that people would no longer understand us, musically." In the latter part of the 1960s, Dennis started writing songs for the Beach Boys. Dennis's collaborator Gregg Jakobson commented, "He started taking his piano playing more seriously. He'd ask Brian to show him stuff until he got a pretty good grasp of chords." In January 1967, Dennis recorded the original composition "I Don't Know", but it was left unreleased. Music historian Keith Badman states that whether the piece was intended for Smile is not definitively known. In December, Wilson recorded a piece called "Tune #1" that was intended for a solo project to be released on Brother Records, but it was also shelved. Wilson's first major released composition was "Little Bird", issued in April 1968 as the B-side of the "Friends" single. "Little Bird" and another song, "Be Still", were co-written with poet Stephen Kalinich and featured on the album Friends (June 1968). The group's next album, 20/20 (February 1969), marked the emergence of Dennis as a producer, including his original songs "Be with Me" and "All I Want to Do". Dennis's "Celebrate the News" was released as the B-side to the standalone single "Break Away". By this time, the Beach Boys' popularity had faltered considerably. Dennis believed, "Because of the attitude of a few mental dinosaurs intent on exploiting our initial success, Brian's huge talent has never been fully appreciated in America and the potential of the group has been stifled. [...] If the Beatles had suffered this kind of misrepresentation, they would have never got past singing 'Please, Please Me' and 'I Wanna Hold Your Hand' and leaping around in Beatle suits." In 2018, many of Wilson's unreleased tracks from this period were released for the compilations Wake the World: The Friends Sessions and I Can Hear Music: The 20/20 Sessions.

On April 6, 1968, Wilson was driving through Malibu when he noticed two female hitchhikers, Patricia Krenwinkel and Ella Jo Bailey. He picked them up and dropped them off at their destination. On April 11, Wilson noticed the same two girls hitchhiking again. This time he took them to his home at 14400 Sunset Boulevard. He recalled that he "told [the girls] about our involvement with the Maharishi and they told me they too had a guru, a guy named Charlie [Manson] who'd recently had come out of jail after 12 years." Wilson then went to a recording session; when he returned later that night, he was met in his driveway by Charles Manson, and when Wilson walked into his home, about a dozen people were occupying the premises, most of them young women. They were later known as members of the "Manson Family". By Manson's own account, he had met Wilson on at least one prior occasion: at a friend's San Francisco house where Manson had gone to obtain marijuana. Manson claimed that Wilson invited him to visit his Sunset Boulevard home when Manson came to Los Angeles. Wilson was initially fascinated by Manson and his followers, referring to him as "the Wizard" in a Rave magazine article at the time. The two struck a friendship, and over the next few months, members of the Manson Family – mostly women who were treated as servants – were housed in Wilson's residence, costing him approximately $100,000 (equivalent to $ in). Much of these expenses went on cars, clothes, food and penicillin injections for their persistent gonorrhoea. This arrangement persisted for about six months. In late 1968, Wilson told the magazine Record Mirror that "when I met [Charlie] I found he had great musical ideas. We're writing together now. He's dumb, in some ways, but I accept his approach and have [learned] from him." He told reporters that he had been living with 17 women; when asked if he had been supporting them, Wilson replied, "No, if anything, they're supporting me. I had all the rich status symbols – Rolls-Royce, Ferrari, home after home. Then I woke up, gave away 50 to 60 percent of my money. Now I live in one small room, with one candle, and I'm happy, finding myself." Wilson introduced Manson to a few friends in the music business, including the Byrds' producer Terry Melcher. Manson recorded numerous songs at Brian's home studio, although the recordings remain unheard by the public. Band engineer Stephen Desper said that the Manson sessions were done "for Dennis [Wilson] and Terry Melcher". In September 1968, Wilson recorded a Manson song for the Beach Boys, originally titled "Cease to Exist" but reworked as "Never Learn Not to Love", as a single B-side released the following December. The writing was credited solely to Wilson. When asked why Manson was not credited, Wilson explained that Manson relinquished his publishing rights in favor of "about a hundred thousand dollars' worth of stuff". By another account, Manson was paid cash and given a BSA motorcycle in exchange for songwriting credit. Around this time, the Family destroyed Wilson's Ferrari, as well as his Mercedes-Benz, which had been driven to a mountain outside Spahn Ranch.

Growing fearful of the situation, Wilson distanced himself from Manson and moved out of the house, leaving Manson and his followers there, and subsequently took residence with Gregg Jakobson at a basement apartment in Santa Monica. Virtually all of Wilson's household possessions were stolen by the Family; the members were evicted from his home three weeks before the lease was scheduled to expire. When Manson subsequently sought further contact, he left a bullet with Wilson's housekeeper to be delivered with a threatening message. Commenting on rumors that suggested Wilson had become afraid of Manson, Beach Boys collaborator Van Dyke Parks later said: Conversely, band manager Nick Grillo said that Wilson became more concerned after Manson had got "into a much heavier drug situation... taking a tremendous amount of acid and Dennis wouldn't tolerate it and asked him to leave. It was difficult for Dennis because he was afraid of Charlie." Writing in his 2016 memoir, Mike Love recalled Wilson saying he had witnessed Manson shooting a black man "in half" with an M16 rifle and hiding the body inside a well. Melcher said that Wilson had been aware that the Family "were killing people" and had been "so freaked out he just didn't want to live anymore. He was afraid, and he thought he should have gone to the authorities, but he didn't, and the rest of it happened."

In August 1969, Manson Family members perpetrated the Tate–LaBianca murders. Shortly afterward, Manson visited Wilson's home, telling him that he had "just been to the moon", and demanded money, which Wilson agreed to give to him. That November, Manson was apprehended and charged with numerous counts of murder and conspiracy to commit murder. Wilson refused to testify against Manson. He explained, "I couldn't. I was so scared." Instead, he was privately interviewed by prosecutor Vincent Bugliosi. Wilson's testimony was deemed inessential since Jakobson agreed to publicly testify and corroborate Wilson's claims. Melcher later commented that Wilson had not been taken to the stand because the prosecutors "thought he was nuts, and by that time he was. He had a hard time separating reality from fantasy." Bugliosi said that when he attempted to procure tapes of the songs that Wilson had recorded with Manson, Wilson responded that he had destroyed them because "the vibrations connected with them didn't belong on this earth." In the subsequent years, Wilson allegedly received death threats from members of the Manson Family, who telephoned his home and told him, "You're next". In 1976, he commented that "I don't talk about Manson. I think he's a sick fuck. I think of Roman and all those wonderful people who had a beautiful family and they fucking had their tits cut off. I want to benefit from that?" In the 1978 biography The Beach Boys and the California Myth, Wilson acknowledged the interest in his relationship with Manson and said, "I know why [he] did what he did. Someday, I'll tell the world. I'll write a book and explain why he did it." According to biographer Mark Dillon, "Some attribute [Wilson's] subsequent spiral of self-destructive behavior ― particularly his drug intake ― to these fears and feelings of guilt for ever having introduced this evil Wizard into the Hollywood scene." Wilson's first wife Carole Freedman later told journalist Tom O'Neill that Wilson and other members of the Hollywood community had closer associations to Manson than what had been reported on the public record. O'Neill quoted Freedman saying that "It's a scary thing, and anyone who knows anything will never talk." Upon Wilson's death, Manson was quoted as saying, "Dennis Wilson was killed by my shadow because he took my music and changed the words from my soul." Manson never elaborated on these claims, but was most likely referring to the lyrical changes in "Never Learn Not to Love".

From August 13 to late October 1970, Dennis shot his parts for the Universal Pictures road movie Two-Lane Blacktop. The film depicts "The Driver" (James Taylor) and "The Mechanic" (Wilson) driving aimlessly across the United States in their 1955 Chevy, surviving on money earned from street racing. It made its worldwide premiere on July 7, 1971, in New York City. The film received mixed reviews but later gained stature as a "cult classic".

Dennis continued writing songs for the Beach Boys' subsequent albums, including Sunflower (August 1970), which featured the single "Forever" – commonly regarded as one of his finest songs – and three others: "Slip On Through", "Got to Know the Woman", and "It's About Time". Their inclusion was said to be at the insistence of Warner-Reprise, who felt that Dennis's songs sounded more contemporary than other rejected Beach Boys tracks. "Slip On Through" became the first of Dennis's songs to be issued as an A-sided single by the Beach Boys. • Illustration — Wilson c. 1971 In the early 1970s, Wilson recorded material with Beach Boys touring musician Daryl Dragon to be set aside for a potential solo album, provisionally titled Freckles. Dennis also offered Poops and Hubba Hubba as the album's working titles. On December 4, Stateside/EMI released "Sound of Free", a single issued only in Europe and the UK under the credit "Dennis Wilson & Rumbo". The B-side was the Sunflower outtake "Lady" (also known as "Fallin' In Love"). At the Beach Boys' concerts in 1971, Dennis played solo piano renditions of his songs "Barbara" and "I've Got a Friend". Biographer Jon Stebbins writes, "He was developing a power-ballad style that would become his signature." Dennis's two song contributions to the Beach Boys' August 1971 album Surf's Up – "4th of July" and "(Wouldn't It Be Nice to) Live Again" – were left off the record. At the time, Dennis stated that he "pulled" the songs off the record because he did not feel they flowed well alongside the other tracks. According to band manager Jack Rieley, the absence of any Dennis songs on Surf's Up was for two reasons: to quell political infighting within the group concerning the album's share of Wilson-brother songs, and because Dennis wanted to save his songs for a solo album. Engineer Stephen Desper said of Dennis's album, "ninety percent of it was ninety percent done". Fred Vail, the band's co-manager, described the album as "diamonds never cut and polished", and explained, "The Beach Boys obviously weren't buying into his songs as part of the group output." Several tracks from the album – "Baby Baby", "It's a New Day", "I've Got a Friend", "Behold the Night", "Hawaiian Dream", "Medley: All Of My Love / Ecology", and "Before" – were released on the 2021 box set Feel Flows. In June 1971, Dennis injured his hand badly enough to prevent him from playing drums for some time, so Ricky Fataar took over as the group's drummer between 1972 and 1974. Stebbins writes, "Now, during concerts, the impulsive, physically aggressive Dennis would be reduced to sitting behind a keyboard or standing off to one side behind a microphone. It hurt him deeply. He felt like a caged animal. His drinking became worse and his participation in the band became erratic." Biographer David Leaf wrote that, by this time, "Dennis was constantly quitting [the band] or getting fired and then rejoining." Two more songs intended for Dennis's album – "Make it Good" and "Old Movie" (retitled "Cuddle Up") – were ultimately placed on the Beach Boys' 1972 release Carl and the Passions – "So Tough". Dennis wrote and produced two songs – "Steamboat" and "Only with You" – on their next album, Holland (1973). A third song, "Carry Me Home", was left off the record. The cover of their 1973 live album, The Beach Boys in Concert, depicts only Dennis onstage, although the album itself contains none of his songs.

Wilson's onstage antics (including streaking) occasionally disrupted the Beach Boys' live shows. He continued recording for his forthcoming solo album at the band's Brother Studios facility in Santa Monica. In 1974, concurrent with the success of the greatest hits compilation Endless Summer, Dennis returned to his role behind the drums. According to Billy Hinsche, keyboardist for the Beach Boys' supporting band, it was during this year that Dennis co-wrote the lyrics and modified part of the melody of "You Are So Beautiful" while attending a party with Billy Preston. Hinsche said, "I was there that night, and I would not dispute that Dennis had a hand in writing 'You Are So Beautiful,' and that's the reason we would do it in concert." By 1977, Dennis had amassed a stockpile of songs he had written and recorded while factions within the Beach Boys became too stressful for him. He expressed, "If these people want to take this beautiful, happy, spiritual music we've made and all the things we stand for and throw it out the window just because of money, then there's something wrong with the whole thing and I don't want any part of it." He then approached James William Guercio, owner of Caribou Records, who stipulated "a structured recording process" before signing Dennis to a two-album contract. According to Guercio, "My discussions with Dennis were along the lines of, 'You just tell Gregg [Jakobson] what you need - you have the studio and your job is to finish the dream. Finish the vision. Trish Roach [personal assistant] will do the paperwork and Gregg's the co-ordinator. It's your project... You've got to do what Brian used to do. Use anybody you want - it's your decision and you're responsible." Dennis released his debut solo album Pacific Ocean Blue in 1977. Although it sold moderately, ultimately reaching No. 96 on the US Billboard chart, its chart peak outperformed the following two Beach Boys albums. Dates were booked for a Dennis Wilson solo tour, but these were ultimately cancelled when his record company withdrew concert support. He did occasionally perform his solo material on the 1977 Beach Boys tour. Despite Dennis claiming the album had "no substance", Pacific Ocean Blue received positive reviews and later developed status as a cult item, ultimately selling nearly 250,000 copies. The album remained largely out of print between the 1990s and 2000s. In June 2008, it was reissued on CD as an expanded edition. It was voted the 2008 "Reissue of the Year" in both Rolling Stone, and Mojo magazines and made No. 16 on the British LP charts and No. 8 on both the Billboard Catalog chart and the Billboard Internet Sales chart.

Pacific Ocean Blue follow-up, Bambu, began production in 1978 at Brother Studios, with the collaboration of then Beach Boys keyboardist and Dennis' close friend Carli Muñoz as songwriter and producer. The first four songs officially recorded for Bambu were Muñoz's compositions: "It's Not Too Late", "Constant Companion", "All Alone", and "Under the Moonlight". The project was initially scuttled by lack of financing, Dennis' physical and mental decline due to alcoholism and severe drug abuse, which stemmed from his severe economic and marital problems at the time, and the distractions of simultaneous Beach Boys projects. Bambu was officially released in 2008 along with the Pacific Ocean Blue reissue. This material was also released on vinyl in 2017, without Pacific Ocean Blue, for Record Store Day. Two songs from the Bambu sessions, "Love Surrounds Me" and "Baby Blue", were lifted for the Beach Boys' L.A. (Light Album) (1979). Dennis and Brian also recorded together apart from the Beach Boys in the early 1980s. These sessions remain unreleased, although they are widely bootlegged as The Cocaine Sessions.

• Illustration — Dennis drumming with the Beach Boys in 1983 Towards the end of his life, Wilson's growing abuse of alcohol, cocaine and heroin was strongly affecting his personal life. Concurrently, creative differences within the band had led to a breakdown of relationships. Following a confrontation on an airport tarmac, he declared to Rolling Stone on September 3, 1977, that he had left the Beach Boys: "They kept telling me I had my solo album now, like I should go off in a corner and leave the Beach Boys to them. The album really bothers them. They don't like to admit it's doing so well; they never even acknowledge it in interviews." Two weeks later, the dispute was resolved, and Dennis rejoined the group. In January 1981, Brian's then-girlfriend and nurse Carolyn Williams accused Dennis of enticing Brian to purchase about $15,000 ($ in) worth of cocaine. When Brian's bodyguard Rocky Pamplin and the Wilsons' cousin Stan Love learned of this incident, they physically assaulted Dennis at his home. For the assault, they were fined about $1,000, and Dennis filed a restraining order. By the last year of his life, he had virtually lost his normal speaking voice, struggled to sing and perform at concerts and his appearances at Beach Boys performances became sporadic. As the Beach Boys pressured Brian to admit himself into Eugene Landy's 24-hour therapy program, Dennis was informed by friends that he would be the band's next target, to Dennis's disbelief. The band gave him an ultimatum after his last performance in September 1983 to check into rehab for his alcohol problems or be banned from performing live with them. By then, he was homeless and living a nomadic life. He checked into a therapy center in Arizona for two days, and then on December 23, 1983, checked into St. John's Hospital in Santa Monica, where he stayed until the evening of December 25, 1983. Following a violent altercation at the Santa Monica Bay Inn, Dennis checked into a different hospital in order to treat his wounds. Several hours later, he discharged himself and reportedly resumed drinking immediately. On December 28, 1983, Dennis drowned at Marina Del Rey after drinking all day and then diving in the afternoon to recover his ex-wife's belongings, previously thrown overboard at the marina from his yacht three years earlier amidst their divorce. Forensic pathologist Michael Hunter believed that Dennis experienced shallow-water blackout just before his death. On January 4, 1984, Dennis's body was buried at sea by the U.S. Coast Guard, off the California coast. Dennis's widow, Shawn Love, reported that Dennis had wanted a burial at sea, and his brothers Carl and Brian did not want Dennis cremated. At the time, only veterans of the Coast Guard and Navy were allowed to be buried in US waters without being first cremated. However, Dennis's burial at sea was made possible by the intervention of US president Ronald Reagan. In 2002, Brian expressed unhappiness with the arrangement, believing that Dennis should have been given a traditional burial. The Beach Boys released a statement shortly after the burial ceremony: "We know Dennis would have wanted to continue in the tradition of the Beach Boys. His spirit will remain in our music." His song "Farewell My Friend" was played at the funeral.

Wilson married his first wife, Carole Freeman, on July 29, 1965; he adopted her son Scott from her previous relationship, and they had daughter Jennifer together before divorcing in 1967. His second wife was Barbara Charren, with whom he had two sons, Michael and Carl; he wrote "Lady" and "Barbara" for her. Dennis was then married twice to actress Karen Lamm, the former wife of Chicago keyboardist Robert Lamm, in 1976 and again in 1978. In 1978, following a Beach Boys concert in Arizona, Dennis was arrested for sharing drugs and alcohol with a 16-year-old girl in his hotel room. Dennis referred to the incident as a setup and paid $100,000 in legal fees. From 1979 to 1982, Dennis had a relationship with Christine McVie of Fleetwood Mac. Fleetwood Mac's 1982 songs "Hold Me" and "Only Over You" were written by McVie about Dennis. McVie later said of Dennis, "Half of him was like a little boy, and the other half was insane." Mick Fleetwood, who had introduced the couple to each other, wrote that "Chris almost went mad trying to keep up with Dennis, who was already like a man with twenty thyroid glands, not counting the gargantuan amounts of coke and booze he was shoving into himself." At the time of his death, Wilson was married to (but separated from) Shawn Marie Harris (born on December 30, 1964), who claimed to be the daughter of his first cousin and bandmate, Mike Love, although Love disputed the claim. Wilson and Shawn had one son, Gage Dennis, born September 3, 1982.
