The song was a conscious homage to the emerging reggae movement (lyrical reference: "life goes on bra"), possibly related to the growing Jamaican population in Britain, although it is heavily blended with Honky tonk. Aside from the syncopated beat, the song also employed meter schemes and devices not used in their previous works, and demonstrated the group's highly experimental nature at the time of its recording. The light-hearted lyrics tell and retell the story of a couple named Desmond and Molly; the simple, upbeat lyrics are often punctuated by laughter, shouts, and sounds that accompany the lyrics in the background.
The second time that the story is retold, the names are switched around in certain places. McCartney described the switch as a slip of the tongue; he decided to keep it in because none of the other Beatles wanted to run through the song again. Longtime Beatles associate Pete Shotton, who was present at the session, confirmed Paul's statement that the switch-up was accidental in his memoir The Beatles, Lennon and Me. Nigerian musician/singer Jimmy Scott later claimed that the phrase "Ob-La-Di, Ob-La-Da" was originally his; Scott sued McCartney for compensation for using the phrase in the lyrics and as the title of the song. According to McCartney, "Ob-La-Di, Ob-La-Da" merely was a common saying of the Yoruba tribe, and Scott had simply taught the saying to McCartney. It reportedly means "Life goes on", words which are also heard in the song. The case was settled out of court.
