"Rock and Roll" is a song by English rock band Led Zeppelin, which was first released as the second track of their untitled fourth album in 1971. As the title suggests, the song is based on one of the most popular structures in rock and roll, the 12 bar blues progression (in A). "Rock and Roll" stands as one of the best-known songs in the band's catalogue.
Led Zeppelin guitarist Jimmy Page has said that this song came to be written as a spontaneous jam session, whilst the band were trying (and failing) to finish the track "Four Sticks". The tapes were rolling and fifteen minutes later the basis of the song was down.
The beginning drum beat was possibly inspired by "Keep A-Knockin'" by Little Richard, or by the identical drum line from "Something Else" by Eddie Cochran.
