<P> There is some uncertainty over who produced the song as Spector took the credit as the producer on many tracks and' B' sides that were produced by Medley . However, Medley, who had produced the duo before they signed with Spector and Philles, consistently stated that he produced this recording . Spector was primarily interested in producing singles and "Unchained Melody" was originally intended to be an album cut . Medley said: "Phil came to me and asked me to produce the Righteous Brothers albums because he would have taken too long and it would have cost too much money ." By Medley's account, Spector only claimed production credit after it supplanted "Hung On You" as the hit . Early copies of the single did not credit a producer for "Unchained Melody" and only credited Spector as producer of the original single "Hung On You". Later pressings of the single credited Spector as the producer . </P> <P> Hatfield made a change to the song during the recording sessions . Hatfield initially recorded a couple of takes of the song as it was written, but returned later for another session, changing the melody for the "I need your love" line in the final verse, and sang it much higher instead . Hatfield then said he could do another take better, to which Medley replied: "No, you can't ." Medley played the Wurlitzer piano on the song and he noted that "if I knew that it was gonna be a hit I certainly would have brought in a better piano player ." </P> <P> "Unchained Melody" reappeared on the Billboard charts in 1990 after The Righteous Brothers' recording was used in the box office blockbuster film Ghost . Two versions charted in the US that year--the original and a new recording . According to Medley, he was interested in having the original recording released due to the renewed interest in the song, but was told that there were licensing issues . Although Hatfield was no longer in the same condition vocally as when he first recorded the song, they decided to re-record the song for Curb Records . The re-recorded version was released as both a cassette single and a CD single . It received minimal airplay but recorded excellent sales, peaking at number 19 . The re-recorded version was certified Platinum by the RIAA on January 10, 1991, and received a Grammy Award nomination . </P> <P> The 1965 original Righteous Brothers recording was reissued in 1990 by oldies - reissue label Verve Forecast under licensing from Polygram Records (which had acquired the rights years earlier). The original version received a lot of airplay, and topped the U.S. adult contemporary chart for two weeks in 1990 . However, sales were minimal in the US since it was only available as a 45 RPM single and the song peaked at No. 13 based largely on airplay . For eight weeks, both versions were on the Billboard Hot 100 simultaneously and the Righteous Brothers became the first act to have two versions of the same songs in the Top 20 at the same time . This re-released song reached number 1 in the UK where it stayed for four weeks, becoming the UK's top selling single of 1990 . As of 2017, it has sold 1.17 million copies . The 1990 reissue also reached number 1 in Australia, Austria, Ireland, the Netherlands, and New Zealand . </P>
