“It Tears Me Up” was released by Percy Sledge in 1966. It was his third single (after “When a Man Loves a Woman” and “Warm and Tender Love”). It’s a great song and a great performance. Most people only remember Sledge for “When a Man Loves a Woman” but he made many fine records. The song was written by Dan Penn and Spooner Oldham. Penn released his own version in 1995.
