Thanks for the story, Guest. That finally makes the song clear to me. The sign that says "Salt Pork" merely points the way to the town, it doesn't mean Louis is IN Salt Pork. (Not that I believe there ever was such a town.)

I enjoyed Janie's link to the video with Louis Jordan, but if I were the director, I would have done something about that glum-looking drummer at the back right of the screen.
