Teacher and performer, Kiri Te Kanawa to sing Saturday in D.C. I 'm 65," says Kiri Te Kanawa, the golden-toned, New Zealand-born soprano. "I can't say the voice sounds like it did at 35. But as long as I do music that suits me, I'm fine. If you're a size 12 you don't try to wear a size 8, do you? You'd look very stupid."
