"When a Man Loves a Woman" is a song written by Calvin Lewis and Andrew Wright and first recorded by Percy Sledge in 1966 at Norala Sound Studio in Sheffield, Alabama. It made number one on both the Billboard Hot 100 and R&B singles charts. Singer and actress Bette Midler recorded the song 14 years later and had a Top 40 hit with her version in 1980. In 1991, Michael Bolton recorded the song and his version peaked at number one on both the Billboard Hot 100 chart and the Billboard Adult Contemporary Singles chart.

The song was initially recorded by Percy Sledge at Rick Hall's FAME Studios at Muscle Shoals, before being re-recorded at the nearby Norala Studios owned by Quin Ivy. The sidemen for the recording included Spooner Oldham, Farfisa organ; Marlin Greene, guitar; Albert "Junior" Lowe, double bass and Roger Hawkins, drums. Andrew Wright and Calvin Lewis did not play on the record. Rick Hall arranged a distribution deal with Atlantic Records, but Jerry Wexler asked that the song be re-recorded because the horns were out of tune. According to musician David Hood, "They went back in the studio and changed the horns, got different horn players to play on it. But then the tapes got mixed up and Atlantic put out their original version. So that's the hit."
