I think the general fact that Yoko was there all the time (she seemed to linger like an ghost) and the paul vs. george clash "ill play whatever you want me to play or not play at all."
"Why did the dinosaurs die out?" "because you touch yourself at night"
there is also the part where John is trying to get that one guitar part right, I am forgetting the song, I think it's "I Got A Feeling" and Paul is saying it's not smooth enough, and keeps showing him how he wants it with his hands...john is getting more and more angry and then does it extremly choppy.
are you sure it's One After 909?...I haven't seen it for a long time, but that isn't sound right at all...there isn't even a part in that song that matches the guitar part he is doing.
1) Always happy Ringo being bored 2) Paul and George squable 3) Paul tries to explain stuff to John and John just stares coldly 4) Three Beatles happily jamming together, Paul comes in and they all stop
