|I saw "Dear World" in Boston the night "I Don't Want to Know" went in. It was very depressing. Lansbury didn't know the lyrics and was fed them by Don Pippin. And she was sick. And the show was only 90 minutes. At the curtain call, she put her hand on her heart and said, "I'm terribly sorry." I had never seen that before, and I've never seen it since. Yes, a very sad night.
