Father Adam can be had on cassette from  http://www.jeanredpath.com/

"www.traditionalmusic.co.uk" looks good at first sight, until you notice that it's a commercial venture composed almost entirely of unattributed material copied from other people's websites (a lot of it came from this one), with apparantly no effort at all made to acknowledge sources.  As a consequence, it's not only worthless as a resource for anyone who's serious about traditional music, it's actually seriously misleading, and I would stongly advise against using it; at least until the owner takes the trouble to document his material, which is easily done nowadays by anybody who can be bothered.
