Annraoi,I got the info from the liner notes of a C.D. by Garry O'Briain and Padraiugin Ni Uallachain titled " A Stor's A Stoirin". A gael Linn production. A great collection of 36 songs for all ages. I believe Padraiugin Ni Uallachain is a school techer in Dundalk. I'm sure you have heard of her. Her father was a great fount of knowledge on the origins of many traditional songs.
