Thanks, Joe, I'm surprised that link never showed up in my Google search. Ironically, the one comment on that page is from yet another Joe - and I know him, he's from my camp.

The camp in the link is in the Poconos, far from Minnesota. So perhaps it's known and sung elsewhere as well.

And you are sure right about camp song origins - the ones we sing range from centuries old rounds to top 40 hits to everything in between. I've tracked the origins of 90% - and mudcat has been an invaluable help. Thanks to all who have contributed their knowledge here!
