Mariah Carey's "All I Want for Christmas Is You," can be heard everywhere during the holiday season, but you've never seen it performed like this before!

Backstage before Tuesday night's taping of Late Night with Jimmy Fallon, Carey, her host and his backing band, the Roots, put a quirky spin on the pop star's holiday hit by performing the song using classroom instruments.

Adding to the adorable factor: a quartet of kids who pop up occasionally to sing backup.

Even with the unusual additions of a ukulele and xylophone, the song came together in delightful harmony.

The Christmas tune is hard to improve upon, but Carey and friends might have created a brand new instant classic!
