Watch Jimmy Fallon Perform "All I Want For Christmas Is You" With Mariah Carey Feat. The Roots

This may just be the best rendition of Mariah Carey's contemporary Christmas classic "All I Want For Christmas Is You" and here are some reasons why:

  • Christmas sweaters

  • The always hilarious Jimmy Fallon

  • Accompaniment by The Roots, who are playing children's classroom instruments like xylophones, kazoos, and that piano thing that you blow into

  • The queen diva herself, Mariah Carey

  • Adorable kids popping up to sing the group parts!

Those are some of the reasons we'll be playing this over and over until the end of December. Watch the charming video above and tell us if you agree!
