Esmereldy and Frank Novak's Rootin' Tooters perform this song in this supposedly humorous 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.
It's all done in a very Hillbilly fashion, with the er, Tooters dressed in patched-up costumes, and Esmeraldy happily yodeling about how her Pappy was hanged from the tree he had planted.
