WATCH: Mariah Carey, Kids And Kazoos Perform An Adorable “All I Want For Christmas Is You”

Mariah Carey tied up her sneaker heels to do a few runs on Late Night with Jimmy Fallon.

The songbird fluttered in to lend a helping 8-octave range to Fallon, The Roots and a couple of kids as they played Carey’s Yuletide classic, “All I Want for Christmas Is You” on traditional classroom instruments: kazoos, xylophones, wood blocks and at least one recorder.

The results: precious (based on the novel “Diva” by Mimi).
