"When a Man Loves a Woman" is a song 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.
It was listed 54th in the List of Rolling Stone magazine's 500 greatest songs of all time. The sidemen for this recording included Spooner Oldham, organ; Marlin Greene, guitar; Albert "Junior" Lowe, bass and Roger Hawkins, drums.
The song is credited to Calvin Lewis and Andrew Wright, who played bass and keyboards with Sledge. However, the song was in fact written by Percy Sledge himself, but he gave it to Lewis and Wright. (Sledge said this in an interview in the program series "The Sixties" on Swedish Television in 2008.)

It was later covered by Michael Bolton in 1991, whose version also reached number one on the U.S. pop and adult contemporary singles charts (Bolton also received a Grammy Award for this song). Barbara Mandrell recorded a Country version of the song that same year. The song has also been recorded by Art Garfunkel and Luba.
