Idina Menzel Sings “Let It Go” With Jimmy Fallon, The Roots Playing Classroom Instruments: Watch the Amazing Video

Dear John Travolta: This is Idina Menzel. She is a wonderfully talented singer and actress. Remember her name! One night after her live Oscars performance (which was viewed by over 40 million views in the U.S. alone) Menzel, 42, sang an excellent reprise of "Let It Go" with the backing of Jimmy Fallon and The Roots for the Monday, March 3 Tonight Show.

As Fallon, Questlove and other played classroom instruments like a rainbow xylophone, wind chimes and other enhancements, the Broadway, TV and film veteran belted out the now-Oscar-winning song passionately and effortlessly.
