The Righteous Brothers’ 1965 hit “Unchained Melody” evokes thoughts of passion, love and … Demi Moore. In case you’ve forgotten, the song was used in the sensual pottery scene of the 1990 film Ghost. In fact, the movie was so popular that it sent “Unchained Melody” to the top of Billboard‘s adult-contemporary chart for two weeks that year. And now it’s used over and over again at weddings — ghost-free weddings.
