Mariah Carey's version of "All I Want For Christmas Is You" is notably one of the most popular Christmas songs ever. Vocally, she can do no wrong. Mariah recently joined Jimmy Fallon and The Roots for an interesting, yet entertaining cover of the hit.

We see Jimmy Fallon sitting there with the Roots, all decked out in lovely holiday sweaters and surrounded by instruments. Most of the instruments used are ones you'd find in a kindergarten classroom. Jimmy starts singing then is joined by Mariah, who takes the lead on the vocals. There are four adorably children who pop up throughout the video. I think I may prefer this version to the original!
