Lennon completed the writing of "Instant Karma!" in an hour. Eager to record the song immediately, he then telephoned his Beatles bandmate George Harrison and American producer Phil Spector, who was in London at the invitation of Allen Klein, the manager of the Beatles' Apple Corps organisation. According to Lennon's recollection, he told Spector: "Come over to Apple quick, I've just written a monster."
