Mariah performs 'All I Want for Christmas' with school instruments

Mariah Carey has performed an alternative version of her festive classic.

The star sang a rendition of her hit 'All I Want for Christmas Is You' on US chat show Late Night with Jimmy Fallon in a school classroom.



She was backed by The Roots, who played the track using school instruments, while a mini choir of four children provided backing vocals.

Fallon performed on a wood block, tambourine, bass drum and kazoo, as various members of The Roots played the recorder, melodica, bongos, Fisher Price xylophone and sleigh bells.

The chat show host previously performed with Christina Aguilera on a rendition of her single 'Your Body', using office supplies.
