The Oscar's best original song - performed on toy instruments

Oscar winner Idina Menzel stopped by the Tonight Show to show off her stuff – but in typical style from Jimmy Fallon, he put an oddball twist on her performance.
Let It Go, from the animated film Frozen, picked up the award for Best Animated Song at the Oscars. This version, though looks like mighty craic, played with classroom instruments by the very talented group The Roots (and Fallon).
