ever hear of the '31 Chevy Roadster/'68 Camaro prop for the Dean Martin show on T.V. ? AMT Model co. had a "prototype shop" in Phoenix in the '60s and hired Gene Winfield, Sam Foose, Bill Hines and others to do whatever needed to be done.

 
Dean Martin drove the Camaro on stage singing to a song, the dancers danced around and past the Camaro, and removed quick release panels of the Camaro, exposing the '31 Chevy Roadster. 

The music's tempo changed and suddenly it was a thirties hot jazz type number
