Five-time Grammy winner Mariah Carey has teamed up with late-night host Jimmy Fallon and The Roots for a very acoustic version of her hit holiday jingle "All I Want For Christmas Is You" -- toy xylophone and other classroom instruments included.
The gang performed the song as part of Late Night with Jimmy Fallon's series of quirky backstage performances. (Remember Fallon's duet of "Call Me Maybe" with Carly Rae Jepsen?)
This comes a year after Carey collaborated with Justin Bieber on a duet of "All I Want For Christmas Is You." Let the comparisons begin.
