I will not enter into a public feud with Madame Callas, since I am well aware that she has considerably greater competence and experience at that kind of thing than I have.

How nice the human voice is when it isn't singing.

Expressions of disapproval are on a level of vulgarity that cannot be tolerated. The way to express disapproval is to do without applause.
