I saw him skate it live in Stars on Ice! His fun and exuberance infected everyone in the whole arena. He had us all singing. So awesome. Memory interlude over, back to the game.
This is difficult, I believe no one else has ever skated to Let it go. On YouTube there are some videos of Julia Lipnitskaya skating to that although Let it go is not the original music she was skating to...
A few seasons back, there was a brother sister US dance team (Alicia & Stephen Reynolds) whose free skate music was a Piano Guys composition that included an instrumental version of "Let It Go." Apart from that, I can't think of another Olympic eligible skater who skated to it, either in competition or exhibition.
