Once again, I have another version, not too different, and once again, it's by Ed McCurdy. Seems to have pieces of several of the above.

BIG ROCK CANDY MOUNTAIN
On a summer's day, in the month of May, a burly bum come hikin
Down a shady lane, through the sugar cane, he was lookin for his likin
As he roamed along he sang a song of the land of milk and honey
Where a bum can stay for many a day and he won't need any money-O
Cho:
The buzzin of the bees in the cigarette trees, the soda water fountain
And the lemonade springs where the bluebird sings
On that Big Rock Candy Mountain.
Well, the farmer and the son they were on the run
To the hayfields they were bound in
Said the bum to the son, Why don't you come
To that Big Rock Candy Mountain
So the very next day they hiked away, the mileposts they kept countin
But they never arrived at the lemonade tide
Or that Big Rock Candy Mountain-O
Cho

I used to sing this He Was Looking For His Lichen - little naturalist that I was.
We also have the Burl Ives version with the cops having wooden legs.
