Mel Torme and the Mel-Tones sing 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.
It's a swing version of a translated song, and while it's presented very simply, I don't need much more than Torme singing to make me happy.
