The whole cast was great. Bill Burr was great as always, his set was newer material and while it started slow, it really built to a great routine. Sadly, Breuer wasn't really anything different than what you've seen from him in the past 10 years - he does great sounds, but his comedy isn't anything different. Dave Attell definitely had one of the best sets I've ever seen from him, including material about Bin Laden's porn stash (which was discovered that morning!); he's definitely become one of the brighter stars of standup in the past couple of years. Jim Norton stole the show - he's very under-appreciated as a comic, his comedy is hilarious, albeit shocking.
I watch a fair amount of standup and my ONLY complaint about this was that it seemed a little dialed back for this crew (save Breuer, who was what you expected). I would have like to have seen more of all 4 comics up on stage, that was a highlight.
