@ MikeyFingers: It's probably a goose. I heard a live version (only a short clip) played on a real bass in a nasty manner, it could defintely have been Les. It said it was the Frog Brigade or something (I haven't heard their stuff). Trouble is, I came across it at some torrent site, so there's no way know who that was playing. Maybe the guy posting it heard 'Les Claypool is the guy who plays the theme from Seinfeld', and stuck that name on there.
Sorry to make your heart jump like that!!
And on the subject of this theme, I'm sooo tired of watching the show in company of friends(and enemies).Every time that theme plays, they tend to turn around and look at me (I play bass) and go 'that's pretty hot bass playing huh' or some crap. Yeah, that's not bad for a synth!
