Favorite scenes?
Personally, I liked that little snippet right after "I Am the Walrus." John plays with the little kid, and then Ringo loses his mind, it's all very wonderful. That's just one of the few, "Hey, I actually know what's going on now" moments of this movie for me, and it's so adorable that I absolutely love it.
"Your Mother Should Know" was pretty good too, although now I can't walk anywhere with that song stuck in my head without having to resist the terrible urge to do that little rhythmish walk thing they did once they reached to bottom of the stairs, where they all point their toes out and sot of swing with each step. (Of course, I can hardly listen to Revolution without doing my stupid little dance when the chorus comes on, too. And "I Me Mine" leads to me waltzing across the room.)
