It is becoming increasingly difficult to obtain the services of first-class conductors. They are sick and tired of dealing with singers, as I am.

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.

I prefer to remember the happy things over 10 years, the things that went well. Let me see, what did go well?

I never socialized with singers. It's very dangerous if you work with opera... I don't think that in 30 years a singer has entered my apartment.

Confine your kissing to the irresistible.

There are two sighs of relief every night in the life of an opera manager. The first comes when the curtain goes up The second sigh of relief comes when the final curtain goes down without any disaster, and one realizes, gratefully, that the miracle has happened again.
