If you thought this subject was pretty much tied up, here's a new twist. We sang this in camp in Griffith Park, CA when I was growing up. We sang this version:

Over there there's a man with a gun
He'll shoot you if you try to run
So Mr moon, moon bright and shiny moon
Won't you please shine down on'
Please shine down on.
Please shine down on me.

But, see, the real genius is what happens next. Now remember this was the 70s and streaking was big. And it was the 70s. So at the end of the song you were supposed to "moon" the audience. Yup, pull your pants down. Our bunk went up in front of the whole camp at assembly and performed the song in its entirety, stage direction and all
