Sully playing classical piece on piano Edit

When Biff and Sully move the piano, Sully plays a classical prelude (?) when Biff leaves momentarily. Anyone know what classical piece Sully is playing? Thanks! -- User:Dawnsteffler 14:32, October 3, 2010

It's Chopin's Prelude No. 7. — scarecroe 19:10, November 4, 2010 (UTC)
