But we can still see a burgeoning of blues since a lot of blues songs had four lines. Hooker's "Dimples" used a line repeated 5 times and then tagged:

Well, I like the way you walk
Well, I like the way you walk
Well, I like the way you walk
Well, I like the way you walk
Well, I like the way you walk
You're my babe I got my eyes on you.

And the Zip Coon lyrics are closer to a traditional blues format than "Dimples."
