'it was just a little love affair' scene
Was the interupptions and put downs between Cassavetes/Falk and the actress singing scripted or not? At the end she turned to her left and whispered to someone else "he's drunk" and then the scene ends. I can't find anything online saying that scene was ad-libbed, but it had to be with that much beer going around. They were all drunk in real life.
Randy lay there like a slug. It was his only defense.
