(Source: MariahDaily)

People: "Mariah Carey's 'All I Want for Christmas Is You,' can be heard everywhere during the holiday season, but you've never seen it performed like this before! Backstage before Tuesday night's taping of Late Night with Jimmy Fallon, Carey, her host and his backing band, the Roots, put a quirky spin on the pop star's holiday hit by performing the song using classroom instruments. Adding to the adorable factor: a quartet of kids who pop up occasionally to sing backup. Even with the unusual additions of a ukulele and xylophone, the song came together in delightful harmony. The Christmas tune is hard to improve upon, but Carey and friends might have created a brand new instant classic!"

LA Times: "Sometimes words are unnecessary, so skip the rest of this paragraph and click for instant joy. The messengers? Jimmy Fallon, Mariah Carey and the Roots, who got together prior to Carey's appearance on 'Late Night with Jimmy Fallon' to do a version of 'All I Want for Christmas Is You.' The version is wonderful, and will light up the blackened hearts of the Grinchiest souls."

Rolling Stone: "Jimmy Fallon roped the Roots into playing a quirky version of 'All I Want for Christmas Is You' with Mariah Carey last night on Late Night With Jimmy Fallon, performing the song on kid-sized toy instruments including xylophone, bongos, rattlers, wood blocks and more. A chorus of children chime in on background vocals and Carey takes it home with her untouchable voice."

VH1: "The schtick is good, and last night it got better when Fallon and company welcomed Mariah Carey and her adorable children's choir for what has to be the cutest rendition of Mimi's modern classic 'All I Want For Christmas is You' ever performed."

MTV: "Jimmy and The Roots accompany Mariah with classroom instruments you might find in a kindergarten music appreciation class. And did we mention there's an actual children's choir that pops up occasionally to add vocals to the chorus? And while all of this is happening, Mariah still werques her diva hand/'I'm singing an important note' move? Again, WE'RE STILL NOT OVER THIS, and we don't anticipate that we will be for a VERY long time."

ZAP2it: "It's Christmas time again, so you know what that means: Mariah Carey's 'All I Want For Christmas Is You' is going to be playing everywhere you go. There's nothing wrong with that, but Jimmy Fallon recently put a new twist on a familiar tradition. He invited Carey, The Roots and four adorable caroling children to sing a new version of the song, and it's awesome. There's even a kazoo!"

Entertainment Weekly: "Give those Pandora and Spotify holiday playlists a break and turn to Jimmy Fallon, Mariah Carey, and The Roots for your morning cup of (non-alcoholic! or not) cheer. With classroom musical instruments and holiday sweaters in tow, a glamorously gown-clad Carey (you didn't think she'd seriously wear a sweater, did you?) joined the gang for a playful rendition of 'All I Want for Christmas Is You' yesterday on Late Night... The adorable children singing background and Carey's breathy high notes make the video irresistible. I don't know about you, but I'm taking a chug of eggnog anytime Carey sings that song on national television. Mariah early Christmas, everyone!"

Huffington Post: "As usual, she sounded impeccable. Maybe she can grace the American Idol audience with those world-class pipes of hers."

Gawker: "...The rendition she performed on last night's Fallon, alongside Jimmy Fallon, the Roots, and a chorus of actual children, is by far the best spin put on this thing since the Phil Spector-inspired original. Few people could pull off the classroom-instrument arrangement with the grace of the 'eternally 12' Mariah, and if there's any perfect time to act like a child, surely it is Christmas."
