Is This the Most Adorable Version of "Let It Go" Yet?#frozen
Idina Menzel and Jimmy Fallon cover the Oscar-winning song.
The jam session rendition of "Let It Go," complete with classroom and toy instruments, may be the most adorable version yet (and definitely beats this one by WKRC's Bob Herzog). Other famous visitors to Fallon and The Roots' music room include Robin Thicke and Miley Cyrus.
"Let It Go" won the Academy Awards for Best Original Song on Sunday, adding to "Frozen's" extremely successful 2014 awards season, during which the song also took home the Golden Globe and the Critics' Choice Awards, among others.
Here's Idina bringing down the house at the Academy Awards.
