There are officially released recordings of many different versions by Booker for this song. My playing on this video is mostly based on the one on Spiders On The Keys (Live At The Maple Leaf Bar, New Orleans, LA / 1977-1982).
It is always fascinating when Booker plays songs with very simple chord progression and shows how much we can do with them. I believe that the key to "Booker sound"- apart from the tone quality - is the details. I’m listening to his playing right now as I write this article and am already finding tiny ghost notes I had never noticed. I will have to make updated version of this song sometime!
