Early on I thought that Paul's confession that he felt uncomfortable imposing (trying) his will on the other 3 to work on the music together was a real "wow!" moment for me. He seemed to really be trying to hold the whole thing together. George wasn't impressed and John and Ringo seemed aloof to the whole thing.
Truth be known he'd been imposing his way since the Magical Mystery Tour days and by then the others had enough.
John playing The Third Man theme was nice.
