In 1967, Gorcey's image was to appear in the crowd of celebrities on the cover of the Beatles' album Sgt. Pepper's Lonely Hearts Club Band, but because he requested a fee, he was removed. Me and the Dead End Kid, a book about Gorcey written by his son Leo, Jr., was published in 2003. In 2017, a third book on his life appeared, Leo Gorcey's Fractured World by Jim Manago, which included an examination of Gorcey's use of malapropisms in the Bowery Boys films. Also in 2017, Richard Roat, known for having the largest collection of Dead End Kids/Little Tough Guys/East Side Kids/Bowery Boys memorabilia in the United States, published the book, Hollywood's Made-to-Order Punks: The Dead End Kids, Little Tough Guys, East Side Kids and the Bowery Boys, complete with photographs, behind-the-scenes trivia, and interviews with the surviving Dead End Kids/Little Tough Guys/East Side Kids/Bowery Boys that he had collected since the 1980s.
