The sound sample that harpgirl provided didn't work for me, but I found a few others at Yahoo! Shopping > Music. Here's what I transcribed:

SALT PORK, WEST VIRGINIA

Macneill, Macneill, don't steal my automobile.
I'll take you to a café and buy you a real fine meal.
Hey, Jack, I got to do some ridin'.
Soon we got to come to a dividin'.
I don't want to continue*
'Cause the sign says, "Salt Pork, West Virginia."
That's where my baby lives, and I ain't goin' no further.
Hey, don't you stop me now. I don't want to commit no murder.
Macneill, Macneill, don't steal my wheel...

*pronounced "continya" to rhyme with "Virginia".

Recorded by Louis Jordan and by Clarence "Gatemouth" Brown.
According to ASCAP, written by William J. Tennyson, Jr., but AMG attributes it to "Moore/Tennyson".
