It's too old to reply directly to, but in response to Ray Pellerin's comment about this being a Stones record ahead of its time, they haven't made this record yet, and by 1978 they quit trying. Not that their subsequent records were bad or all bad--they just didn't attempt this kind of thing anymore.
So good ! I perform H&L with the band I'm in ( The Cliffnotes ) . Play harp and sing . I throw in a few more high bends . The genius of Jimmy Reed songs is how adaptable they are for almost every player's interpretation, yet are met with favor and popularity by listeners
