The Curse Word The Beatles Left in the Middle of 'Hey Jude'
Given all the instruments, microphones, and other moving parts used in studios, it’s obvious why recordings don’t come out flawlessly. And The Beatles had plenty of blemishes and other unintended accidents turn up on their albums.
Sometimes, the band was happy to leave in the mistake. A famous example came in the recording of “Ob-La-Di, Ob-La-Da” during the White Album sessions. In the final verse, Paul McCartney sings that Desmond (rather than Molly) stays at home and “does his pretty face.”
Instead of re-recording the vocal part, Paul decided to leave it in for fans to wonder about. A few weeks after the Fab Four finally wrapped up “Ob-La-Di, Ob-La-Da,” the band was recording another classic track with a few hitches: “Hey Jude.”
This time around, the problem didn’t come in the lead vocal. However, you can hear background noise (spoken words, in fact) about halfway through the hit single. And you can hear a Beatle drop the f-bomb in that moment.
