“Unchained Melody” by ...... Les Baxter .... not who comes to mind first, even if it was first.
n 1954, Alex North was contracted to compose the score for the prison film Unchained (released in 1955). North composed and recorded the score and then was asked to write a song based upon the movie’s theme. North asked Hy Zaret to write the lyrics. After first refusing, Zaret and North together wrote “Unchained Melody.”[10][11] Zaret refused the producer’s request to include the word “unchained” in his lyrics.[12]
