The lyrics to that one are tough to get a handle on. A while ago I tried and didn't get too far. But, the music is basically identical to "Les Barres de la Prison", as recorded by Canray Fontenot, and others. Chris and Sean Ardoin did a nice zydeco version of it, with an accordion part that is very, very similar to what Boozoo does. I suggest you use "Le Barres de la Prison". If you don't have the lyrics for it, let me know and I will post them. I sing this song at nearly every gig!
As to the rhythm, it is all solid 3/4, except for the fact that Boozoo jumps time now and then. It is just Boozoo's idiosyncratic way of playing that makes it sound crooked. It is a tribute to his band how seamlessly they covered for him. Just play it straight 3/4 and it will be fine.
