I bought three from amazon.ca, the Canadian wing of Amazon. They have French and French Canadian material not listed on Amazon.com.

The hard-bound "Chants de Marins a la decouverte d'une tradition vivante," 2003, includes a 73 minute cd with 25 tracks from earlier albums; there are three tracks of Hugill and three of John Wright; the rest are in French. It cost $46 Canadian.

The complete catalogue of books and cds is available from

Many Breton cds, other than chanteys, are available.

(Another thread has some of the same info, but I can't find it)
