This is terrible, terrible news. I have corresponded and spoken with Margaret in so many countless places over the last 30 years or so - beginning at one of Jerry's museum concerts back in the 1970s. She is one of the few who can claim to be not just a performer but a careful and methodical scholar of the traditional material in which she specialized. She has given us a wealth of material that might otherwise remain stored away in dusty libraries and archives. There aren't words adequate to express my sorrow.
