Meet Derek.  He's 1/4 of a doo wop quartet called The Whiptones from Whippany, New Jersey.  Derek decided to put his acapella skills to good use when asking his friend Gina to prom.

Derek's brain child takes the art of prom proposal to a whole other level!

Derek surprised Gina at a restaurant, and the result is adorable.

The Whiptones performed a version of the Cadillacs' "My Girlfriend" – with some clever, custom lyrics – to woo Gina. But did she say yes?
