Idina Menzel performed Frozen's Oscar-winning smash "Let It Go" on Monday's Tonight Show, with a little help from Jimmy Fallon and The Roots. They covered the song using "classroom instruments."
The 42-year-old theater star visited the late-night show in New York City directly after arriving home from her trip to L.A. for the Oscars, where she performed the song for the first time ever on live TV.
Fallon sat beside Menzel, tapping a trio of alphabet blocks. The Roots backed the stars up with a variety of instruments, including the xylophone, kazoo, tambourine, ukulele and keyboard harmonica.
The host previously hosted similar jam sessions with Mariah Carey, covering the modern holiday classic "All I Want for Christmas Is You," and Robin Thicke, covering his No. 1 smash "Blurred Lines."
During his opening monologue, Fallon poked fun at John Travolta butchering Menzel's name at the Academy Awards. "He could tell as he was saying it, 'This is not going to come out right at all—I'm gonna say sounds,'" he joked. "When Idina Menzel heard that, she was like, 'Let it go. Let it go. Let it go.'"
