Even having had years of Norma Waterson's ill health, in which it was only a matter of time until her suffering was ended, it hits me someplace deep and heavy that she has died.
The Watersons, with Martin Carthy, were touring in aid of "Sound Sound Your Instruments of Joy" when I saw them, live, in Cambridge, Massachusetts, a long time ago.
It was many years later when I discovered the fiction of Terry Pratchett with his own fantastic way of evangelizing and spreading the word about England's traditions. And, regarding Pratchett's Sisters of Wyrd, I always saw the character Nanny Ogg (playing the banjo in the bathtub) as a cross between Margaret Barry and Norma Waterson.
