In the 1975 Beatles discography "All Together Now", the song was classified as a Beatles studio outtake from mid-1967 with "intriguing lyrics woven around very complicated beat changes." Later speculation suggested that it was a demo made at home, presumably by John Lennon with George Harrison and possibly Paul McCartney, using a Brenell tape recorder that each Beatle owned. The recording date has been placed as early as 1966 (reflecting the early psychedelia of some "Revolver" songs) or as late as 1968 (based on similarities to the guitar style on "Dear Prudence"). If the lyrics are interpreted as describing an LSD experience, the phrase "lately has been banned" places the song's origin no earlier than August 1966 when LSD became a prohibited drug in Britain.
