Entertaining thread. Many useful references, but reminds me of Mark Twain's observations about science - a massive return in speculation for a trifling investment of fact! :-)

Given that it was widely enough known to be used in the Saturday Evening Post in 1875, and for everyone to jump on when recording in the '20s, it's a bit surprising to me that there's no printed version in sheet music or song sheets in the American Memory collection. Perhaps it was *too* widely known?
