The live mass singalong was televised on ABC's "Good Morning America."
The program also featured a video montage compiled from viewer submissions of small children singing the tune.
Idina Menzel, the Tony Award-winning actress who sings the song in the movie, was also on hand to lead the live singalong. She will sing the song live at Sunday's Oscar ceremony where "Frozen" is up for Best Animated Picture as well as Best Original Song.
