They have a new production of The Trojans at Covent Garden, which is wonderful, and some of the singers, I was visiting with them backstage, and one of the singers came up to me and said, “My agent told me he was at the Met when you did both parts. How in the world could you do both parts? I’m exhausted after singing Cassandra.” I said, “Well, you have to carbo load the night before. You have to prepare for that the way a marathon runner would prepare to run for 26 miles. Why anybody would want to run for 26 miles is beyond my understanding, but that’s something else again! So you have to prepare your body to have enough stored energy upon which you can call, once the day arrives that you’ve got to do this. So I eat in a completely different manner when preparing for something that’s going to happen like that the next day.
