After posting this, I was wondering why I did, other than my warped sense of humor. I think it's because when I think of Robertson, I think "yahoo". He's an ignorant prick, only after the glory of fame and the almighty dollar. In any event, this song popped into my mind.
Go figure.
Can you imagine this guy (Lil Jimmy Dickens) sitting in church as a young boy, making up these lyrics with his friends after having heard the melody hundreds of time?
My friends and I used to do the same thing.
Edited to add: He and his friends were probably thinking of the traditional country Sunday dinner, especially during the depression. Butter beans were plentiful and filling, cooked with some ham hock for flavor. Add some cornbread, yummm.
