Idina Menzel, Jimmy Fallon sing "Let It Go" with classroom instruments

Fresh off her performance at Sunday's Oscars (and John Travolta's hilarious -- and cringe-inducing -- mispronunciation of her name) Idina Menzel stopped by "The Tonight Show" to sing her hit song "Let It Go" from Disney's "Frozen."

The actress got a little backup from "Tonight" host Jimmy Fallon and The Roots, who accompanied her on classroom instruments like a triangle, xylophone, tambourine and even some toy blocks.

Menzel (or should we say Adele Dazeem?) looks like she's having a great time singing the tune, which won the Oscar for best original song during the Academy Awards telecast. "Frozen" also picked up the win for best animated feature film.
