Princess Momokai sings the title song in this musical short.
It's one of more than two thousand "soundies" produced between 1939 and 1947, meant to be played on a device called a Mills Panoram. For seven years they could be found in bars, night clubs, and other places where people would gather. Think of them as music videos, available for viewing at a dime a song. Other companies got into the production end also.
The song was popular enough that it was used in a Bugs Bunny cartoon. It's a rare instance of Hawaiian swing music, and the Princess -- if she really was one -- rattles off the syllables like a tongue twister.
