Redd Harper mugs it up and sings -- assuming that's his voice -- in a basso that makes B. S. Pulley sound like a little boy in this amusing 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.
Harper does a few things that make me think he was imitating Red Skelton. Quite funny.
