I accidentally stumbled upon his page while doing my searched on Breton music. Then I realize not only that the information is in French(I am just beginning to study that language) but there is nothing much info on the web other than the fact that he teaches music in north Brittany. So I called his number and talked to him. He doesn’t speak English so I talked to his girlfriend  who was very helpful and she said that if I can email him the questions then she will help him out. Very interesting turn of events.
