Rock 'n' Roll is the sixth solo studio album by English musician John Lennon. Released in February 1975, it is an album of late 1950s and early 1960s songs as covered by Lennon. Recording the album was problematic and spanned an entire year: Phil Spector produced sessions in October 1973 at A&M Studios, and Lennon produced sessions in October 1974 at the Record Plant (East). Lennon was being sued by Morris Levy over copyright infringement of one line in his Beatles song "Come Together". As part of an agreement, Lennon had to include three Levy-owned songs on Rock 'n' Roll. Spector disappeared with the session recordings and was subsequently involved in a motor accident, leaving the album's tracks unrecoverable until the beginning of the Walls and Bridges sessions. With Walls and Bridges coming out first, featuring one Levy-owned song, Levy sued Lennon expecting to see Lennon's Rock 'n' Roll album.

Harvey Phillip "Phil" Spector was an American record producer and songwriter best known for his innovative recording practices and entrepreneurship in the 1960s and his two trials and conviction for murder in the 2000s. Spector developed the Wall of Sound, a production style that is characterized for its diffusion of tone colors and dense orchestral sound, which he described as a "Wagnerian" approach to rock and roll. He is widely regarded as one of the most influential figures in pop music history and one of the most successful producers of the 1960s.
