I was a supernumerary in her 1980 Met ELEKTRA (one of many unseen screaming servants), and around for rehearsals. What a sweet and funny lady she was! And, yes indeed, that voice! She was one of opera's real human beings. They're all too rare these days. And yes, she did once come to a WALKURE rehearsal in a miner's hat (winged, yet). Reportedly her point was noted and the lighting was adjusted.
