Look, it wasn't an exact cover of the song...so there's no need to get angry about this. As much as I LOVED 'Frozen,' even I am sick of hearing its most popular song. Pearl Jam doing it, though? Okay, fine...I'll watch.
It should be pointed out that this in the middle of "Daughter." Isn't that how most dads know about "Let it Go?" Because of their daughters? I'm just type-rambling. This happened in Italy.
