Here is another text of this song from ~1958.
~
MOTHER HUMPERS BALL
(Tune - Darktown Strutters Ball)
Oh there's gonna be a ball at the Mother Humpers Hall
The witches and the bitches gonna be there all
Now honey don't be late, cause they're passin out the pussy, bout half past eight
Now I've humped in France and I've humped in Spain
I've even been humped on the coast of Maine
But the best piece I ever saw
Was when I humped my mother in law
Last Saturday night at the Mother Humpers Ball
