Watch Mariah's Disney World 2004 Christmas performance

It's been six years since Mariah last performed at the Disney World Christmas Parade "All I Want For Christmas Is You. This year she is back to promote her soon to be released holiday album "Merry Christmas II You," where she will be pulling out all the stops to ensure that her new album featuring "Oh Santa" delivers and can match the success of her now classic holiday album "Merry Christmas," released in 1994 (click here to view videos from that album).
