Meet The Aristocrats. Or, the A'Cats for short. They're Washington University's all-Disney a cappella group. Yup. All Disney. All the time. (Check out their site here.)
The A'Cats were founded in 2005. And according to their website, they are the "newest and one of the sexiest a cappella groups ever." Disney and sexy. Two words you just don't see together often enough.
No luck tracking them down on YouTube. Anyone got a video?
