JAM-BOWL-LIAR, is, of course, a parody of Hank Williams' JAMBALYA..

Homer & Jethro's recording appears on their album "America's Song Butchers: The Weird World of Homer & Jethro," Razor & Tie CD #2130, 1997.

It's also on YouTube, which is where I heard theses lyrics:

JAM-BOWL-LIAR
As sung by Homer & Jethro

Goodbye, ma'am. We gotta scram down the highway.
Stick out your thumb, you son-of-a-gun. Goin' my way?
I got a ride with a guy in a wagon,
In a sack in the back that he was a-draggin'.
Jam-bowl-liar, shoo-fly pie, an' bananner puddin',
'Cause tonight I'm a-gonna see ol' Sally Goodin.
Danced all night; on my feet wore a blister.
Had to sidetrack her nose when I kissed her.

On the couch side by side we was settin',
And just about the time we started a-pettin',
Some big hick throwed a brick through the winder,
Hit her side, hurt her pride, broke my finger.
Jam-bowl-liar, horse-meat pie on a push-cart,
Flipped my lid, always did love that red heart
It was rough. The meat was tough. I chewed it slow.
Almost choked when some bloke hollered "Whoa!"

Jam-bowl-liar an' a pizza pie an' a bowl o' soup beans,
Spotted ham and a can o' choc'late-coated sardines.
When we sing, it sounds just like a cat-and-dog fight,
But we don't sing for money, just for spi-ite.
