I love how when they performed this song for the 50th anniversary, literally no one (well except maybe Bruce) was singing the same part they did on the studio recording. For the live version, Al was singing Brian's lower part, Jeff was singing Brian's higher part, Brian was singing Carl's part and David was singing Mike's part. Wild!
That's an incredibly cool observation.
Is there any other song in the band's catalog that, when played live, as many parts were swapped and sung by other BBs official members live when compared to studio? (not counting Brian's band or M&B, where the majority of singers are non BBs official members).
