Zappa talks about the Captain Beefheart/Grunt People movie, Donnie Vliet and Grown So Ugly and Don’s carved werewolf head. I think the date, 1969, is correct and it seems to have been recorded as a radio show. If anyone has more detail about when, where etc., please let us know.
Some time ago Barry’s Imaginary Publisher produced a poster to be used as a prop in the documentary film, Freak Out in Cugamonga. There is a short illustrated article about the making of the poster, Captain Beefheart vs. The Grunt People, at moonbug.org. Copies of the poster are now available from Cafe Press, priced at $19.99.
