Their music stopped suddenly in the middle of their program. They completed it without music and won the gold. That performance earned a standing ovation. Actually, they did have to skate it again, with the music. But they were perfect, with or without.
I do believe I have seen footage of that on television as part of 'specials' about skating, or possibly it is on one of my purchased video's that tell some of the history of skating. Definitely amazing.
