Buddy McGregor: "The next scene to be filmed was where the guys lean out of the window and a fellow in a Buckingham Palace uniform, carrying a gun or a hose, goes by. Their dialogue was to read something like, 'Where are you going? What are you doing down there?' But, they could not get the line out. They would break up and giggle and whack each other with their elbows. There were about thirty takes for this little scene and they just could not get it done. So, the director decided, 'That's enough. We've been at this since very early this morning,' so he called a halt to the day. Frankly, the Beatles were just too high to continue shooting."
