One of the most soulful songwriters/artists. If you haven't gotten into his music you're due for a treat when you do. There's a slew of his tunes on utoob.
He wrote It's All Over Now and he complained bitterly to another R and B artist (I think Chuck Berry) that the RS version was getting all the praise and the attention and not the Valentinos' version (his band) and he was told to be grateful that the RS had covered it, not just for the royalties he was getting.
