I’m from Boston and learned some of these song from my grandmother when we went camping and some from school. It’s funny how we all learn different versions (some are much better). This is one that I saw many different ways. This is how I learned it:

In the land of mars, where the ladies smoke cigars
Every breath they take, its enough to kill a snake
When the snakes are dead, they put roses in their head
When the roses die they put diamonds in their eye.
When the diamonds break then it’s 1968
