Lane Truesdale and a backing group perform a hot version of the novelty song. Meanwhile, a portrait of a man in a big black beard moves his eyes to take a look at Miss Truesdale's shaking derriere in this soundie.
Soundies were short films, generally about three minutes in length, meant to be played on a Mills Panoram. These devices were installed in bars, nightclubs, and other location that you might find a regular jukebox. Instead of just the record playing, you got a performance. More than two thousand of these short movies were produced from 1940 through 1946.
It's a good musical number with a racy visual content.
