You can't only have names from rock and pop - Patitucci is much more of a star than several other 'big names' we've had, but he's a jazzman, innee, so too technical, too out there, etc. so that doesn't count, does it?
Incidentally, when one of the household names of bassdom, John Taylor of Duran Duran, attended the show a few years ago, people still found reason to complain for the opposite reasons to Patitucci's presence, that is, because apparently his talk was swamped with former Duranettes, so he didn't play much bass, he didn't talk much technique, and chose to reminisce and present his book instead.
They can't win, can they?
