If it's updated information you want, this interview is pretty good.

I thought of recommending this interview on another, more recent thread. But that thread is called Norma Waterson Unwell, and it would make people panic to see the thread-name again. So leave that thread be, and add to this one.

I've never seen Norma live, only her husband Martin Carthy.
