I went to the opera practically every night. I went to something practically every night, just learning and seeing and absorbing, and what I noticed is that there were singers that were only sort of slightly older than I whose voices sounded as though they were many decades older than that, and didn’t sound pretty, and I needed to understand what was happening. I mean there were singers that were 28 or 30 years old or something, and I would speak to them afterwards to say, “Was your voice tired tonight? Tell me what’s happening,” because I didn’t understand it. Their voices should have sounded fresh and blooming and wonderful, but instead they sounded different, and it was because they were singing a different opera every night, and singing whatever was offered, and I didn’t understand and needed to understand — because no one was telling me these things — why they just didn’t say no. Why didn’t they just say, “Oh no, I don’t think I should.”
