Well, I just read through all of the threads (from beginning to end). I can see why people would find it easy to believe in the Black Plague Theory. But alas, if some of you, whom seem to have put your first entry over two years ago haven't found any evidence then I doubt I'll find any soon. I have a two-year-old and so my interest has thus been sparked because I'm not sure if I want her to sing it. But if I don't let her I want it to be because there is evidence that it is an incantation or a rhyme about half the world's population dying from some dreadful disease (even tough it seems I can dismiss this theory). Yes, I find I now tend to think about some of this folklore a little differently now that I have an impressionable little one myself.
