Before I begin, the answer is NOT Pitch Perfect 1 or 2. I'm looking for a movie that is centered around a school competition of competing teams. The only thing I remember is the ending where one girl is singing on stage with a video of her mother who was a previous member of the group. I know it sounds a little like pitch perfect 2 but I definitely remember that it was a video of her mother. I think there was some kind of theme like "through the years" or "generations," Something like that. Please help, it's driving me nuts.
