Well, I play in a tribute band. Here are some of our videos.

I don't feel like I'm using this to rip off people or to cash in on Floyd's fame and hard work, none of us do...but then again, I have pretty much had it with playing for nothing for no one, too old and there is not enough time left in my life for that. The life of a drummer is much different than the life of a singer/songwriter.
But what is it when Roger Waters tours with a band that has no original members other than him? Is it splitting hairs then? DOes it need to be every single member playing every single note?
"Authenticity" is a bunch of shit. Bob Moses comes across as an angry guy. He "knows Mingus" more than you, so there...ah, blooey...
