Of course Beyonce sang "At Last" for Barack and Michelle Obama's first dance at the Neighborhood Inaugural Ball.
Mariah Carey also took the stage, singing the very appropriate "Hero." The performances didn't stop there, as Stevie Wonder, Mary J. Blige and Black Eyed Peas' will.i.am wowed the prez, while Queen Latifah made a special appearance.
