I interviewed her a few years ago for my radio program on WFDU-FM.
Very pleasant voice, interesting stories and knowledge of her material, and I would certainly go see the show!
She recorded a number of songs for a series of films on the bagpipe that aired on PBS a few years ago. Mostly traditional, but some original songs dealing with historical events. I enjoyed it. (The name of the films escape me at the moment).
The Gordon Gunn band who you also mentioned are also wonderful on CD! I hope they come through the NYC/NJ area!
