As time goes on, we discover things we didn't know about. Thanks to Oliver Stone, we know about how three of the Doors allowed Buick to use "Light My Fire" in a commercial without the permission of the Lizard King, but before they released their first album they score part of a training film for Ford Motors.
This film is reminiscent of the Chevrolet training film Hired, which was featured on Mystery Science Theater 3000. This one focuses on Ford service department employees, rather than sales people. It features a nightmare sequence about different kinds of difficult customers.
I believe that one of the actors in this film is Bill Williams, the star of 50s TV shows The Adventures of Kit Carson and Date with the Angels, however I can't confirm this. I do know one of the main actors in this is Frank Coghlan Junior, who played Billy Batson in The Adventures of Captain Marvel and was the repairman in the Curtis Mathis television ads of the 70s.
In the nightmare sequence, the voice over belongs to Frank Nelson, best know for being the foil of Jack Benny, Lucille Ball and Redd Foxx, as well as the chauffeur in the commercials for McDonalds' Passport To Riches contest. Unfortunately, he doesn't say his famous "YYYYEEEEESSSSS" catchphrase.
Another thing missing is Jim Morrison's vocals. However, did perform some percussion and sound effects, possibly some of the "voices" of the customers.
Listen carefully, you can pick out early versions of such Doors songs as "I Looked At You," "Soft Parade" and "The End."
