If you haven't listened to his interview with Robin Williams yet, do so. I actually went into it wondering how much of it I'd be able to stand, but it was actually pretty good, even though Mr. Williams did go off on a tear or two.
I enjoyed that, of course recently I read a book about the old Comedy Store days, so it was interesting to hear him talk about them.
I also liked the opening monologue where Maron expresses some regret about putting Williams down in the past.
It was rather surprising that Williams was for the most part a bit on the soft-spoken side. Guess for whatever reason he didn't feel obliged to go on too many tears during the interview.
Also: mentions of Sam Kinison, and mentions of cocaine, but no mention of the Sam Kinison cocaine story.
