This is a pleasant enough one gag musical short. Both the music and the story work, but you'll be amused, not impressed.
The curiosity here is the singer (and lead), Vyola Von. She is in her late teens or early twenties, bouncy, sort of cute, not a great singer and not a great beauty. About 15 years later, she reappears as Veola Vonn with small roles in a number of full features. Now she plays a strikingly attractive and very shapely sexpot, often a Frenchwoman busily seducing the likes of Lou Costello or Huntz Hall. You have to look closely to determine that it is the same person. She doesn't seem to have had any extensive cosmetic surgery, she just has filled out, aged very well, and plays a different character.
