Watching this film feels like you are in the room where the magic is made. Jam sessions end up like a greatest hits album that slots into place right before your eyes. Ringo is a good listener and the best drummer for this band. McCartney just bangs out major songs one after the other, it's unbelievable, so is the mucking about and mayhem. It seems like they all turn up every day and jam, mess around and leave at the end of the day with a couple more songs, great songs that become standards. They have a shorthand with each other that everyone else doesn't get. That's from years of playing together in clubs and all of the huge records that they created just by being mates and slotting together like a precision watch. Brilliant.
