Unchained Melody is a 1955 song with music by Alex North and lyrics by Hy Zaret. North used the music as a theme for the little-known prison film Unchained, hence the name. Todd Duncan sang the vocals for the film soundtrack. It has since become one of the most recorded songs of the 20th century, by some estimates having spawned over 500 versions in hundreds of different languages. Sam Moran sings this song on his Colour of Love album.
