When I was a kid in the late 70's- early 80's, I saw a movie about a little girl and her father who put on a puppet show with huge puppets. Well, the puppets had huge heads anyway. The little girl and the father would sing a song that went something along the lines of "The show must go on, if you feel good or not, the show must go on". In the movie,t he father dies and the little girl has to put the show on without him and she sings the song to herself for courage.
I have thought about this movie for years and that song has recently taken on new meaning to me.
Anybody know what it is?

Was wondering about this movie too, I remember the girl was orphaned after her father died and that she was reunited with a family member at the end ( a brother I think, since she remarked how tall he had gotten since she saw him last).
