I’ve only heard one recording of Opel, and I found her high notes disappointing. That being said, she was very young (probably about 25 in that recording) and was more of a soprano in her youth. After all, she did go on to play Hope Harcourt, and she must be the only woman to play both Eva Peron and Hope Harcourt in professional productions.
When I see the phrase "the ____ estate", I imagine a vast mansion in the country full of monocled men and high-collared women receiving letters about productions across the country and doing spit-takes at whatever they contain.
