Yer Blues

Lennon said that, while "trying to reach God and feeling suicidal" in India, he wanted to write a blues song, but was unsure if he could imitate the likes of Sleepy John Estes and other original blues artists he had listened to in school. In "Yer Blues," he alludes to this insecurity with a reference to the character Mr. Jones from Bob Dylan's "Ballad of a Thin Man," and with the third verse, which draws on Robert Johnson's "Hellhound on My Trail". Instead, Lennon wrote and composed "Yer Blues" as a parody of British imitators of the blues, featuring tongue-in-cheek guitar solos and rock and roll-inspired swing blues passages. The half-satirical, half-earnest song mockingly acknowledges the British blues boom of 1968 and the debate among the music press at the time of whether white men could sing the blues. According to Walter Everett, the song's "ponderous earnestness... belies the composer's satirical tone." In the chorus, Lennon sings, "If I ain't dead already, girl you know the reason why." Beatles biographer Jonathan Gould interprets this to be a "joke [in] that nobody knows the reason why—or, for that matter, what any of these bluesy poetics are really supposed to mean." Gould called "Yer Blues" an example of the "cultural realism" that distinguished the Beatles from their musical contemporaries in Britain: "[T]heir acceptance of the idea that, except as a subject of self-parody, certain expressive modes of African-American music lay outside the realm of their experience and hence beyond their emotional range as singers." The song is in the key of E major, but like many blues numbers, it prominently features accidentals, such as Gnatural, Dnatural, and Bflat. It is primarily in a time meter, but as with several of Lennon's tunes, the time signature and tempo are altered many times.

Coinciding with the 50th anniversary of its release, Jacob Stolworthy of The Independent listed "Yer Blues" at number eight in his ranking of the White Album's 30 tracks. He wrote of the song: "This track sees Lennon take on the blues to deliver a song that stands tall among the greats he attempted to emulate (see: Sleepy John Estes, John Lee Hooker). The result is evidence that Lennon rarely did wrong – even when he himself half expected to."

"Yer Blues" was recorded in EMI Studio Two's "annexe," which was actually a large closet in the control room. In 2016, Paul McCartney recalled, "We were talking about this tightness, this packed-in-a-tin thing. So we got in a little cupboard – a closet that had microphone leads and things, with a drum kit, amps turned to the walls, one mic for John. We did 'Yer Blues' live and it was really good." In interviews for The Beatles Anthology series, Ringo Starr affectionately recalls recording this song in the stripped-down conditions, saying it was like the old days of live performances by the Beatles. The stripped-down, bluesy nature of the number bears similarity to much of Lennon's early solo output, including "Cold Turkey" and his 1970 John Lennon/Plastic Ono Band album and marks a retreat from the concerns that Lennon had with such studio experimentation as had marked songs like "Tomorrow Never Knows" and "Strawberry Fields Forever." The track, along with "Glass Onion", "While My Guitar Gently Weeps", "Mean Mr. Mustard" and "Sun King", is one of few Beatles songs on which Paul McCartney used a 1966 Fender Jazz Bass rather than his better-known 1963 Höfner 500/1 Violin Bass or his 1964 Rickenbacker 4001S-LH (Fire-glo) bass. Contributing to the live sound of the recording, loud yelling between band members can be heard in the instrumental tracks.
