This soundie for the song "Who's Yehudi?" dates from circa 1942. This novelity song is based upon a running gag by Jerry Colona from Bob Hope's radio show. Colona would constantly look for a mythical and invisible figure named Yehudi. Yehudi soon became synonmous with anything hidden or invisible. There was even a Project Yehudi during WWII for the camoflauge of ships and airplanes.
