 I'm Bill Black with another Bet You Didn't Know music fact. Here's an oldie but goodie by Luther Vandross. It's a song that everybody loves, but I bet you didn't know. This song was the inspiration for the movie House Party. Writer and director Reginald Hutland explains. I was packing to go back to college and the radio was on and the Luther Vandross song Bad Boy Having a Party was on.
