That link shows they used to sell the cd -- so the stuff got onto cd -- but the current site, http://www.celticrose.com/, doesn't list it. But it's here. Not obvious who the publisher is. The big guys (Elderly and Andy's Front Hall) don't have it. I bet Mr. Greenhouse (Camsco) could get it, though, if you asked. :-)I'd been wondering about that too, found recently that that's one of the tapes that dying in my collection.
