No, it's not every musical theme in this voiceless documentary of the 1980 Winter Olympics at Lake Placid in New York. But one of the ice dancers does his bit in a spangly outfit to a disco beat. Even though that's halfway through, it certain sets a tone.
It's one of the shortest Olympic documentaries I've looked at. I suspect the reason for that was the events surrounding the 1976 Olympics. It's hard to celebrate international amity and friendly competition after terrorists have just massacred an entire team. So the film makers, given the short length of the finished film, chose to show the Olympics with music and allow the spectators, who show up around the 20-minute mark, to serve as the movie audience and have a good time for us.
