Oh man, this has totally given me a headache, more so every time someone tries to explain that "my father" wrote the "correct" or "official" version, without clarifying which version they mean. Sorry mates, I still don't get what you're after legally--royalties or just corrected credit, or suppressing certain versions which you consider inferior or a copyright infringement?   

But what I've really just been trying to figure out: is South Uist the Dark Island? Or is it a real place at all? Or....?
