I have a recording from a group in Ohio fromback n=in the eighties that have the lyrics as: Always marry an ugly girl, that's the only kind, she'll never ever leave you but if she does you wont mind. This is the chorus.

Then it goes on day an ugly girl was born her pap took it on the chin, he held her up , turned her around and said MY LORD WE GOT TWINS.

mY QUESTION IS IS THIS SONG PUBLIC DOMAIN?
