The original song "When a Man Loves a Woman" was written by Calvin Lewis and Andrew Wright and first recorded by Percy Sledge in 1966. It was recorded at Norala Sound Studio in Sheffield, Alabama, and became a number one hit on both the Billboard Hot 100 and R&B singles charts. The song was originally titled "Why Did You Leave Me Baby" and was later renamed "When a Man Loves a Woman" after some changes to the lyrics and arrangement during its creation process. Percy Sledge's powerful and emotional performance made it a timeless classic in soul music history.
