You know I gotta agree with you, I often considered that bit of distortion added a bit to it. I found some Otis at the local libary, The man had it goin' on.
he is singing just so wonderfully here. He's one of the greatest of all blues singers and the equal of Muddy Waters, with whom he played as a 'sideman' pianist for so long. Littlle Water could not sing so good. But Otis Spann, could.
