Muttley: So, in short - I quoted correctly - did I suggest you didn't? No. I said that I have heard other explanations & have reason to doubt the interesting ones you were kind enough to post. The fact that what you're quoting is in a book in university libraries isn't concrete proof. I wasn't having a go, I'm just not convinced.

But I'll try to lay hands on that book sometime...
