 According to Norm Rossington, in the scene where John takes the  scissors and cuts the tailors tape and says "I now declare this  bridge open." John improvised other versions where instead of  "bridge" he would say "Synogouge", "Fish and Chips Stand", etc. Also  of interesting note, the tailor in the scene is the Beatles real  tailor. Another nugget: In the same scene, when Norm and Shake walk  into the room, theres a copy of John Lennons book "In His Own  Write" on the shelf (the black book with the picture).
