Been looking for one not listed here: The Girl From Possum Holler (tune of Girl from Ipanema) All I can remember is

Short and fat and squat and ugly
The girl from Possum Holler goes walkin
And when she passes, each one she passes goes
Bleeecch

When you see her walkin from the back
It looks like two pigs fightin in a 'tater sack
And when she passes, each one she passes goes
Bleeecch

Oh, wow that girl is so ugly
She has an excess of ugly
How can one girl be so ugly
Every day when she walks to the crick
Even the (catfish?) get sick....

Not sure about that last line. I'm trying to think back 40 years here!

BTW, when Homer died, Jethro did a wonderful job working with Steve Goodman for quite a few years.

Blessings!
