twocats, If you're doing either the "intermediate", "easiest", or "easy" versions from the first post, they all indicate that eighth notes are swung (see the top of the score). If the goal is to try your hand at blues, it probably better that you're working on one of those versions, since the WC Handy version (the "Harder" version) is kind of a mix of genres, and not what we might consider a typical blues nowadays. Working on swing is great--classical players tend to be a little stiff on swinging. (OH, it just occured to me that maybe you are playing the WC Handy version, and you wrote "easier" when you meant "harder". There are definitely sections in there to practice swing as well!)
It's been a week since I'm back from vacation, so maybe it's time for a progress recording. A bunch of caveats because I'm little embarrassed sharing something so incomplete. I'm playing an electric piano with noisy keys. I decided to sing a little. Everything needs work, but the singing especially! I improvised the arrangements for the A and B sections, but I'm probably not going to do an improv over the C section (the blues); instead, I'll work up an arranged "solo" and steal heavily from Dr. John. I don't feel comfortable enough with this style yet to really improvise. In the recording, the last 30 seconds are improv, but that's only because I forgot to start singing at the right place!!

I decided to add the A section after listening to the sweet Fats Waller version that Diretonic found.
If anyone's interested: I think I found the Professor Longhair recording that inspired the Dr. John recording I'm studying. So there are now two recordings to intensely study!
