A live version appears on her 1985 album, Patti.

It peaked at number two in the UK Singles Chart. It also topped the Canadian Singles Chart. Seal recorded the song for his 2008 album Soul, and, in April 2009, it became his first top - ten Adult Contemporary hit since `` Love 's Divine '' in 2004 ; the song was subsequently nominated for the Best Male Pop Vocal Performance Grammy. Rod Stewart also included this song on his 2009 album Soulbook. The song was chosen as one of the Songs of the Century by the RIAA.
