That's very sad news indeed...I visit the Glen every year and always played a few sessions with James and Connie in Roarty's or Biddy's. Not only was James highly regarded as a Donegal fiddler, but also did a lot of work with local kids, passing on the tradition.
Despite the fact that i play the whistle and speak only a little Irish, he was always happy to talk with me, and accompany my tunes etc. A very gentle man, maise!
