Look for a group called, I think, Tri Yann. They probably sing in all three languages of Brittany - French, Breton and Gallo. You should also check out Dastum, the agency which collects and publishes Breton traditional song. I have a sampler CD here which they publish to get the songs circulating.

Also, there are probably a large number of French language Breton songs sung in Quebec. You might check that out by reading books by Marius Barbeau.
