The Dark End of the Street was written by Dan Penn and Chips Moman in 1966. The original (and probably the best and most famous) version was released by James Carr in 1967. Percy Sledge also released a version in 1967. It has been covered numerous times and I have attached links to YouTube below. It was used in the 1991 film The Commitments. Co-author Dan Penn released a version in 1994.
