To say that Caballé, whose strongest register was her middle, didn't have the middle notes to sing Norma is ridiculous. Caballé's legati in "Casta diva" are seamless. Check out her "Casta diva" on her "Montserrat Caballé Sings Bellini and Donizetti" CD. Fleming could learn a thing or two! She sounds afraid of the moon goddess instead of praying to her. Her Italian has badly rolled r's.
