Idina Menzel "Lets It Go" With Jimmy Fallon and the Roots the Day After the Oscars

Broadway's Idina Menzel (Wicked, If/Then) has the kind of voice that doesn't need any more musical backup than a lemon-shaped baby rattle and a triangle. So her rendition of Frozen's "Let It Go" was the perfect choice for one of Jimmy Fallon and the Roots' adorable children's-toy song covers.

The Tonight Show performance had a lot on Sunday's Oscar rendition. For one thing, there's not one butchered pronunciation of the Tony winner's name in this whole recording, and for another, with just a set of wooden blocks, Jimmy manages to keep way better time than the Oscar orchestra did.
