I can only remember one verse (sung to Battle Hymn of the Republic)-

I watched him climb the mountain like a mountain goat
I saw him as he slipped and fell and tumbled down the slope
I saw him as he hit the rocks and like a pumpkin broke
and his head went rolling on

Gory gory what a hell of a way to die
Gory gory what a hell of a way to die
Gory gory what a hell of a way to die
and his head went rolling on

There was a lion hunter, a soldier in the trenches, and many others all different ending "and his head went rolling on"

I found a couple of others like it here but not that one
