Idina Menzel Sings “Let It Go” with Classroom Instruments on “The Tonight Show”

Idina Menzel, or Adele Dazim as John Travolta so embarrassingly slaughtered it, didn't impress the critics at the Oscars on Sunday, but she definitely made up for it the following night at "The Tonight Show." She sings "Let It Go" with Jimmy Fallon's band who are all playing children's classroom instruments. This one is pretty good.
