This song is a study in using a form that has a ii chord on bar 9 and then goes to the V chord on bar 10 instead of the usual V, IV, I change. This is referred as a ii, V, I change, which is one step closer to becoming jazz. The riff played in the intro and repeated often on bars 9 and 10 outlines this new set grooves. Little Walter used it in songs such as "One More Chance with You" and "Fast Boogie."
