Mariah Carey's 'All I Want For Christmas Is You' is one of the most iconic Christmas tunes, and it's now gotten an adorable makeover with a little help from Jimmy Fallon and The Roots.

It was recorded backstage before 'Late Night with Jimmy Fallon,' and features Jimmy with his band on various classroom instruments, like a kazoo, recorder, and Fisher Price xylophone.


Mariah lends her incredible voice, and some kids pop in with the backing vocals.


Jimmy Fallon always seems so excited to work with celebrities, as if he doesn't realize he's a star himself, which I think is a huge reason why I find him so likeable.
