Music Performances

The AGT winner and ventriloquist took on a favorite James track — "Something's Got a Hold on Me" — with her puppet, Oscar.

They are, in fact, different.

The annual Royal Variety Performance featured Susan Boyle in 2010. 

Long before Snoop or Williams appeared on The Voice, they spun hip-hop gold with "Drop It Like It's Hot."

The Voice Coach alums nailed this Disney classic. 

Judge Howie Mandel told Simon Cowell to "write a check for a million dollars right now" following the group's off-the-hook performance. 

Richard Goodall has come a long way from being a shy janitor singing in the hallways of his school. 

An amazing (grace) cover, indeed, from The Voice alum. 

Kelly Clarkson doing this kind of belting on the fly is so impressive.

The America's Got Talent alum absolutely crushed this grunge-rock classic.
