Julian Cope presents Head Heritage

Zappa as "director on stage" was always part of their dynamic, most obviously on the "Ahead of Their Time" CD where he's literally directing a "play" on stage dressed like an old-time movie producer complete with megaphone.

The liner notes/libretto to "Civilization Phaze III" also describe action to be performed on stage during the music, and there is a character "FZ" who stands at the top of the stage periodically giving orders through a megaphone! Since he was dying as he composed it, apparently he intended for some actor to wear a costume as this character (I picture a "foam rubber giant nose & moustache" outfit!)
