(LIN) - Thank you Gawker for spreading the news of this fabulous holiday video. By far, this is one of the most adorable sing-a-longs going viral out there.

But you can't go wrong, really, when you put Jimmy Fallon, The Roots, a surprise pop-in from Mariah Carey and a bunch of cute kids playing children's musical instruments together. It's a perfect mix. Pure holiday spirit, enough to make almost anyone smile.

From YouTube:

Backstage before the show, Jimmy, Mariah Carey, and The Roots grabbed some instruments you'd find in an elementary school classroom and stopped by the Late Night "Music Room" to sing Mariah's holiday classic, "All I Want For Christmas Is You." (instrument list below)

Jimmy Fallon - wood block, tambourine, bass drum, kazoo
Mariah Carey - vocals
Questlove - wooden clacker w/ afro pick
Mark Kelley - Fisher Price xylophone
Kamal Gray - recorder
James Poyser - melodica
Captain Kirk - ukulele
Tuba Gooding Jr. - kazoo
Frank Knuckles - bongos
Black Thought - sleigh bells
