She sang with Callas and Schwarzkopf and emerged smilingOpera
I once interviewed Elisabeth Schwarzkopf. She spent the first 20 minutes badmouthing the young singers in her masterclass whom she had just subjected to a session of live public abuse.
I never met Maria Callas, but she was reputedly not easy.
Christa Ludwig duetted with them both and emerged smiling.
I met Christa twice in Vienna and she was sweetness itself.
With just a hint of steel.
