Eddie Floyd (born Eddie Lee Floyd, 25 June 1937, Montgomery, Alabama ) is a soul and R&B singer-songwriter, best known for his work on Stax Records in the 60s and 70s. Floyd was unfortunately overshadowed by labelmates such as Otis Redding, Sam & Dave, and Rufus Thomas, although he managed both chart success and touring acclaim. He not only had great hits on his own (most notably the soul music anthem "Knock On Wood"), but wrote songs for others, such as "You Don't Know What You Mean To Me" for Sam & Dave.
