Continuing to find this thread interesting.

Quote: "Tennessee, Arkansas and Mississippi "country blues" ... is played more simply so that the stories can be told without having the music overpower the story, many of which dealt with some very serious subjects..." ... " if you are playing "country" blues you should be able to sit down with other "country blues" players and everyone is pretty much on the same page with not much deviation in structure... You should know where you are supposed to be at any given time in the song..."

Also just wanted to say thanks to Bobert for his personal insights into 'country blues', something I know dick about. It'd be nice to see more discussions on topics like this here.
