Backstage before Late Night With Jimmy Fallon, Mariah Carey and Jimmy Fallon took time to sit down and grab some elementary school instruments and sing along Mariah's Christmas classic "All I Want For Christmas Is You".
Together with The Roots, Mariah and Jimmy went "caroling" using wood block, tambourine, bass drum, kazoo, wooden clacker, a Fisher Price xylophone, melodica, ukelele, bongos and sleigh bells.
Watch the video below:
It's really starting to look a lot like Christmas!
