"A World Without Love" is one of The Rock and Roll Hall of Fame's 500 Songs that Shaped Rock and Roll.

McCartney did not think the song was good enough for The Beatles. Prior to giving the song to Peter and Gordon, he offered it to Billy J. Kramer, who rejected it.

McCartney described John Lennon's reaction to the song: "The funny first line always used to please John. 'Please lock me away –' 'Yes, okay.' End of song."

This song was never released by The Beatles and the only known recording of the song by any member of The Beatles is the original demo of the song performed by McCartney which is now in the possession of Peter Asher.
