Watch: Idina Menzel Gives the "Let It Go" Performance of a Lifetime!

You've sung along in the theater, watched (and commiserated) with every parody out there, and probably can't get it out of your head, but hearing Idina Menzel, aka Elsa from Disney's Frozen, belt out "Let It Go" live during the Oscars is something to behold. And when you consider that she did so after John Travolta butchered her name during his intro, her performance is even more breathtaking. Don't believe us? Just watch the Broadway superstar sing the flick's now Academy Award-winning tune here.
