Mariah Carey, Jimmy Fallon and the Roots Perform Maybe the Best-Ever Rendition of "All I Want for Christmas Is You"

As long as there is Christmas, there will be attempts to spruce up and breathe new life into Mariah Carey's most enduring contribution to pop music, her 1994 holiday classic "All I Want for Christmas Is You." Mimi has sanctioned a a bass version, a house version, an Extra Festive version, a SuperFestive! version with Justin Bieber. But 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.
