Roy Hamilton was an American singer. By combining semi-classical technique with traditional black gospel feeling, he brought soul to Great American Songbook singing.

"Unchained Melody" is a 1955 song with music by Alex North and lyrics by Hy Zaret. North wrote the music as a theme for the prison film Unchained (1955), hence the song title. Todd Duncan sang the vocals for the film soundtrack. It has since become a standard and one of the most recorded songs of the 20th century, most notably by the Righteous Brothers in 1965. According to the song's publishing administrator, over 1,500 recordings of "Unchained Melody" have been made by more than 670 artists, in multiple languages.
