My pipe band is going to be doing an all day seminar and night concert in a couple months to help further our beloved bagpipe music and also the Scottish and Celtic heritage in general. Part of what we're doing aside from giving mini-workshops to the kids on the instruments, music and highland dress is give topic related speeches or presentations to individual classes. Since I speak a little French and am a history buff I was nominated to give a presentation to a high school French class on the Celtic heritage/influence in French Brittany. Can anyone recommend some good reading material? I've got tons on Scotland and the "Auld Alliance" between Scotland and France but nothing I've got mentions much about Brittany at all.

A little help?
