Search google for “Oscar Brandt The Clean Song” and you will find lots of hits.
Common to all the hits will be that they’re sourced to the fortune database. But where is the actual source?
Apparently, the singer is named “Oscar Brand” (no “T” at the end), and the song is called “A Clean Song” (not “The”).
Fun for the whole family?
