Gathering backstage before the show, Carey belted out her Christmas classic with the help of Fallon and The Roots, all performing with instruments found in an elementary school classroom.
The group -- including Fallon, who rocked out using a wood block, tambourine, bass drum and kazoo -- all wore various red holiday garb to perform along with adorable elementary school students.

Originally releasing the hit on her fourth studio album, 1994's Merry Christmas, Nick Cannon's wife Carey -- the mom of twins Moroccan and Monroe, 18 months -- re-released "All I Want for Christmas Is You" in December 2011 as a duet with Justin Bieber.
