Oh, Jon, you do have problems, don't you? Deepest sympathies. (I'm willing to bet a whole dollar that Britten and B&B win.)
Birgit Nilsson was my first Turandot too (but that wasn't my first opera). Turandot seems a curious choice for introducing a 7th-grader to opera. Jon, do you know what your mother's reasoning was for selecting that one?
