The Jonas Brothers: Joy To The World!

The Jonas Brothers keep close together as they rock out on stage for the Walt Disney World Christmas Parade at Disneyland.

The musical trio — Nick, Joe and Kevin — sang a medley of “Joy To The World” and “We Three Kings.”

The JoBros also recently made the cut for MTV’s Rookies and Breakouts of 2008. The networks says, “They have a TV show and some movies, including their foray into 3-D cinema, in the works for 2009, so they may have broken out in 2008 but they’ll soon be ranking as MVPs.”
