The Firesign Theatre's "Everything You Know is Wrong" movie was basically a lip synch of the original album, but one of the main guys working on it was a guy from New Orleans, cinematographer Allen Daviau, who later worked on "Close Encounters", "ET", "Indiana Jones", "The Color Purple", and "Empire of the Sun", among others.
Here are a few highlights of the movie:
"Part 1"
Bear Whiz Beer and Magog Brothers ads
