You've sung along in the theater, watched (and commiserated) with every parody out there [1], and probably can't get it out of your head, but hearing Idina Menzel, aka Elsa from Disney's Frozen [2], 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 [3] 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.
