Did Joan Sutherland ever sing the Queen of the Night aria from Mozart's The Magic Flute?

Answer 1

Yes, she did. Joan Sutherland sang the complete role of the Queen of the Night at the Royal Opera House, Covent Garden in London in January of 1962, with Otto Klemperer conducting. She never recorded the role commercially, but a pirate recording of the January 4th performance has circulated for years. Also, Sutherland made a commercial recording of the

Queen's first aria, "O zittre nicht," for the Decca/London label. It is important to remember that in the three London performances she sang the first aria transposed down a semi-tone and the second aria down a full time. The commercial recording og 'O zittre nicht' is at pitch.
