I remember seeing it years ago on daytime television during the Christmas/summer holidays. That’s a dud ratings period, so it was probably a real C grade film.
It was about an aspiring young female opera singer. She gets her lucky break and makes her debut at some famous opera house (the Met in NY?). It’s a stunning success. Then she gets some sort of throat condition that prevents her from singing for a whole year. Finally she makes another triumphal comeback.
Any ideas?
