I just saw this film a couple days ago. It really made the songs come alive for me, beautifully done! I saw the bum when Martin Luther's character comes to New York and went that should be Joe Cocker - it was! Lots of fun trying to identify all the 1960s references. I am in the process of watching the audio comments now.
Story line is only an excuse for the songs. Covers several years in the 1960s about a British guy with wanderlust meeting an upper crust American girl, love and life in 1960s big city, getting separated and a happy ending. All with great songs.
Love it or not, a good one to see just for the references to 1960s and getting to know the Beatles. *I* loved it!
