In 1966 Stax took a chance and released a Floyd recording of a song he'd written for Otis Redding called "Knock on Wood". It turned out to be Floyd's biggest hit and established him as a leading soul man in his own right. He recorded a number of other northern soul hits such as "But It's Alright" and "Big Bird", which was covered years later by The Jam. He went on to record on Secret Affair's I-Spy label in the late 70s, and then fronted The Blues Brothers Band on a number of tours. And, he's still going strong as evidenced by the video below.
