I think they have: at any rate, the most recent things I've seen about it (QI, a book I got for Christmas, and er... other things I've forgotten) point out that there isn't a mention of the rhyme before the early 19th century and that red circles and sneezing are not symptoms of the plague (unlike buboes in the armpit etc.). Not that I've actually looked into it in detail myself, though.
So much for believing I knew... I learned that it was way older than that, that it originated around the time of the plague, but someone obviously pulled the leg of a whole generation of Norwegian kids. Heh - what a prank... *shakes head*
