From an email I received today:

The reason I happened to log onto Mudcat was because I was looking for my father's version of "The Rattling Bog". In my father's version he always used the word "curious" instead of "rattlin" as in ----- A rare branch and a curious branch ------- a rare twig and a curious twig ----- etc, etc. I'm absolutely positive that he always sung it to us as children using the word curious but alas I cannot find any trace of his version on the net which surprises me.

I've never heard "curious" - has anyone here heard a version with "a rare branch and a curious branch?"
