Revealing mistake: As Paul sings, "And I Love Her" there's a close-up shot of Ringo playing his bongos. The only problem is there are no bongos in this part of the song. (00:49:05)
Revealing mistake: John takes a pair of scissors and cuts the tailor's tape measure as he says, "I now declare this bridge open". Everyone else has left the room but the tailor winks at someone off camera. (00:47:10)
