Rock 'n' Roll is the sixth studio album by John Lennon.
 Released in 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 Record Plant Studios (East).
 Lennon was being sued by Morris Levy over copyright infringement of one line in his 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.
"Rock 'n' Roll Star" is a song by English rock band Oasis.
 It is the opening track from their record breaking debut album, "Definitely Maybe".
 Like the majority of the band's songs from this era, it was written by lead guitarist Noel Gallagher.
 Noel said that "Rock 'n' Roll Star" was one of only three songs in which he wanted to say something: "I've pretty much summed up everything I wanted to say in "Rock 'n' Roll Star", "Live Forever" and "Cigarettes & Alcohol", after that I'm repeating myself, but in a different way".
 It became a fan favourite and was often played to close the band's gigs.
It's Only Rock 'n Roll is the 12th British and 14th American studio album by The Rolling Stones, released in 1974.

 The album also marked the 10th anniversary since the release of the band's debut album, "The Rolling Stones".
 "It's Only Rock 'n Roll" has a firmer rock sound than the band's previous album, the more funk - and soul - inspired "Goats Head Soup".
 "It's Only Rock 'n Roll" reached #1 in the US and #2 in the UK.
