We're not too far apart here. Let's suppose David Benoit appeared in a show and people actually paid to see the dude ONE time.
They'd get their eyeful, realize he's a crap and either demand their cheese back or never watch him again.
The people would be justified by their actions. Your argument suffices, he isn't a draw nor worth the price of admission.
I simply believe people are gullible enough to be interested something asinine, simply to see how big a car wreck it may be.
