In 1970, Elvis Presley took his version to No.2 in the UK, Candi Staton's version only reached No.32 in the UK in 1982. Although I actually prefer Elvis' version, I think that Candi deserved to get higher than she did with her excellent cover version.
Elvis' version is my all time favourite, but Candi's voice has a certain quality of melancholy and sadness that I like and that suits this song very well.
