Mariah Carey tried out a new rendition of All I Want For Christmas Is You that included childhood instruments, hip-hop band The Roots and late-night host Jimmy Fallon.

Showing up on Late Night in a show-stopping red gown, Carey, 42, sat down with the guys to help perform the classic carol complete with recorders, kazoos and a children's choir.

Just last year, Carey remade the famous track with Justin Bieber, and now, she's got a new holiday track out Merry Christmas II You that can be downloaded here: smarturl.it/MCIIYou
