Re: Vinnie Colauita
He also is wearing a "Stuff" t-shirt (Steve gadd's NYC band back in the late 70s/early 80s)for that show. My friend got a copy of the whole thing (German TV special, "We Don't Mess Around") and it's, like anything Zappa, hilariously entertaining and seriously badass.
This is from that same show - Zappa wanted to exploit Vinnie's ability to make a seal/walrus sound and tells him to do a seal call drum solo. The keyboardist Tommy Mars joins in midway on storytelling and accordion.
"Seal Call Fusion Music" -- this should be required listening for all musicians -
