Didn't we see Ken Waller (pumping iron) in the beginning standing on stage? He is definitely not in shape anymore. He has no chest at all :)
When David introduces himself to the lady on skates he says I am David Banner :-) Or was it Bennet? Difficult to tell for me.
A good episode with Lou playing a simple guy, not really confident in his beliefs and trying to find a way to accomplish his dream, opening a restaurant.
I think Lou must have been very nervous playing next to Bix who is one of a kind when it comes to acting and directing.
