Painting of The Mothers of Invention by the great Cal Schenkel
 
This is the footage that matches much of the Ahead of Their Time live album that came out in 1993. It’s essentially a comedy “play” featuring Zappa as “The Imaginary Director” with Mothers Don Preston, Jimmy Carl Black, Bunk Gardner, Roy Estrada, Ian Underwood, Euclid James “Motorhead” Sherwood, Arthur Dyer Tripp III and various members of the BBC Symphony Orchestra.

Filmed on October 25th, 1968. Part of the long out-of-print Uncle Meat VHS release from 1987.
