Idina Menzel and Jimmy Fallon remix 'Let It Go'

"Let It Go" is one of the biggest hits an animated movie has had in years, but dare we say we're partial to this new version.

Idina Menzel showed up on "The Tonight Show starring Jimmy Fallon" on Monday night with her pipes at the ready to perform "Let It Go." Fallon and The Roots backed her up with their oft-used classroom instruments, which includes a toy xylophone, wood blocks and a triangle.

Fallon's pulled this routine before on his old "Late Night" show, convincing Mariah Carey, Carly Rae Jepsen and Robin Thicke to sing more kid-friendly spins on their tunes.

The only thing better than this performance would be if Fallon and The Roots gave us an album full of "Frozen" covers played with kiddie noisemakers.
