Cab Calloway and his orchestra perform the title song in this soundie.
Soundies were short films, about three minutes in length. The were meant to be played on a machine called a Mills Panoram, a video jukebox that was typically to be found in bars, lounges, and similar venues. You put a dime in and got a performance from the ten on the machine. The movies would be changed weekly, and from 1940 through 1946, Mills and other companies produced more than two thousand soundies.
Calloway gives one of his high-energy performances, and does. Bit of scatting towards the end. He was one of the most frequent performers of soundies, and always a delight.
