What Rain Dog gives us, above, is a good sampling of popular verses. Every singer has variants, of course. The late great James Booker (a phenomenal pianist, worth searching out and listening to) was a notorious Angola alumnus and did great versions of this song. I think I can quote a verse, or most of a verse anyway, off the top of my head:

Gimme whiskey when I'm frisky
Gimme water when I'm dry
Gimme cocaine when (something -- sorry!)
And a l'il her-on before I die.

Another verse ended "And run a marijuana farm until 1999." He's sing this, of course, back when '99 seemed to be way off in the future. Booker didn't live to see 1999.

He also usually included references to "The Ponderosa," which was one of the names used for the Angola prison farm.

I'm sorry I can't be there with you, listening along to your Dr.John recording. I'm sure I could decipher his patois for you; at least, I would have enough familiarity with enough different versions that I could deduce what he was saying.
