Other songs on the album are more light-hearted and optimistic, marking the return of Lennon's humour and wit after the uncompromising doctrine espoused on "Some Time in New York City". These tracks include "Intuition", in which Lennon relates how life experience has honed his instincts and how it's good to have gotten through it. While demoing the song on piano in early 1973, with the lyrics still incomplete, he added a few lines from two previously released tracks – "How?", from "Imagine" (1971), and "God", from "John Lennon/Plastic Ono Band" (1970). "Only People" reflects his and Ono's personal philosophy. Lennon later said that it failed as a song, however; in an interview with "Playboy Magazine", he remarked: "It was a good lick, but I couldn't get the words to make sense."
