The Denver Broncos may have a new theme song.
It's a parody of "Let It Go" - and we have to warn you, it will be stuck in your head for the rest of the day.
The new version of the song, was written by a young patient at Children's Hospital named Daniel.
He was the winner of the hospital's parody contest.
As you can see, everyone had a hand in making it quite a production!
