Confine your kissing to the irresistible.

Miss Renata Tebaldi was always sweet and very firm... she had dimples of iron.

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.

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 never for a moment believed they would perform at 10 o'clock in the morning. It's hard enough getting them to perform at 8 at night.

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.
