I am amazed that the New York Times seems to have gotten caught off guard with nothing prepared. It was widely known that she has been battling cancer for years.
In her older and zaftig years, she became a Connecticut fag hag with cache, but she was not really a nice person. The word bitch was a frequent descriptive. I look forward to the officially trotted out obit to see how any of that is handled.
Meanwhile, I have to say, she and Peter and Paul were my earliest music teachers. The first album I owned in this life was Peter Paul and Mary Live at the Bitter End. When they were not tutoring me, I was studying melody and harmony a la Joan Baez and John Phillips and Cole Porter, all infused with Gregorian chant. Not a bad school.
Update: Full obit.
