I was crazy about Kiri Te Kanawa while I was in my twenties and thirties. She is not the greatest singer ever. But her lovely voice is free of the screeching that many sopranos cannot escape. I was disappointed with her recordings of popular songs. They lacked the life that had made the songs so popular.
