John Lennon was the song's composer and singer but the song was credited to Lennon/McCartney. It was originally called "All I Want Is You". Lennon would later comment that he thought the song was "a piece of garbage," though he has shown similar scorn for many of his songs. It was written for his soon-to-be wife Yoko Ono, and featured a multitude of strange, seemingly nonsense phrases which were strung together, culminating in the chorus "All I want is you", aimed at Yoko.
