Mariah Carey Sings 'All I Want for Christmas Is You' with Jimmy Fallon and The Roots

Christmas wouldn’t be complete without Mariah Carey’s “All I Want for Christmas Is You.” In the spirit of the season, the pop diva remixed her holiday classic with some help from “Late Night’s” Jimmy Fallon and The Roots.

Backstage before the show, Jimmy, ?uestlove, and the rest of the band grabbed some classroom instruments and gathered in the “Late Night” music room to perform Mimi’s signature tune.

Mariah took a seat alongside Jimmy in a festive red gown and put her powerful pipes on display, while Jimmy played the tambourine and kazoo. Some tiny tots even joined in to add their vocals.
