Made a couple years before Cinderella hit big with 1986’s triple-platinum ‘Night Songs,’ this ad finds the Philadelphia-based hair-metal band shilling for a local chain of chili dog stands called Pat’s Dogs. Apparently, Cinderella appeared for free as a favor to the Pat’s Dogs owner, an old friend of the band and perhaps one of their biggest fans at the time. One of the band members was a vegetarian so (look closely) one of the buns has no meat inside. No matter, it still manages to be plenty suggestive.
