Haitian Divorce lyrics

I was amazed the way Steely Dan places its lyrics in Haitian Divorce in particular.
Strong and short intro
Strong and short development
Artistic using of incomplete phrases!

Shortly saying the long western story had been placed onto the 5 min masterpiece with few short solo's.

After 'unzipping' the meanings of these slightly weird lyrics, I still didn't figure who is 'Clean Willie'?

Please share if anyone knows!
Please share your experience with other weird Steely Dan's..
