Yeah, that sounds like it would've sucked a bit. Watching Les Claypool live is better than the music sometimes. The guys a freak. As far as being surprised that the crowd was eating it up; you have to remember that most of them were probably on a lot of opiates, etc.
And the set isn't very good IMO, I have seen a lot better by them in the past. Where the FUCK is Tommy the Cat, Southbound Pachyderm and Jerry Was a Racecar Driver?
Trust me, go see Primus when it's not some gimmick show and you will be impressed.
