As I've been writing in another thread, I've started to consider the possibility of them setting the screen tests to an unreleased track. So it could be that they've reworked John Lee Hooker's guitar and added new lyrics.
It did sound so familiar to me as well. I was actually contemplating the task of poking around blues musicians' discographies
Florence!
At least I have a head start now.
