Butter's rendition. As much as I love Kalb, this is the definitive white blues boy version, not getting into the Muddy or James Cotton versions. Stan always says that you have to favor the father over the sons and he was Muddy's manager for a while, so I will defer to him. Wish Stan all the best, dealing with his share. Amazing guy, not to mention photographer. I miss New York. I think that my New York friends divorced me long ago, most of them anyway.
