Oh I'm not interested in a recording of the Black Book. I'm talking with a fellow filker about releasing an album (for fun) where the theme is magic's price. Bethancourt was a friend of hers, so it occurred to me he might have had a song touching on it.
I managed to find an old reference where someone had uploaded simply everything into a university archive, which of course is gone now, but the wayback machine crawled a lot of it. So I've been downloading all day instead of entering CDs into the store. I also found another version of it, courtesy of the wayback machine, that appears a bit edited. Couldn't find it *anywhere* else. Someone had linked it to me at a pagan archive site, but that refused to open for me.
The link you've helpfully provided just happens to be one of the parts the wayback machine didn't crawl. It's fate! ;-)
