Xanadu is the soundtrack to the 1980 musical film of the same name, featuring the Australian singer Olivia Newton-John and the British group Electric Light Orchestra (ELO). It was released in June 1980 on MCA Records in the United States and July 1980 by Jet Records in the United Kingdom. The original LP release featured on side one the songs of Newton-John, and on side two the songs of ELO. In 2008 the soundtrack album was digitally remastered as a bonus CD as part of the film's DVD release titled Xanadu: Magical Musical Edition. Although the film was a critical and commercial disappointment, the soundtrack was a worldwide success and received positive reviews from music critics, earning double platinum certifications in the United States and Canada. The singles "Magic" and "Xanadu" reached number one in the United States and United Kingdom, respectively. It was the fifth most popular US soundtrack of 1981. Background The soundtrack featured songs on side one by the film's star, Olivia Newton-John, written by her long-time producer, John Farrar. The songs on side two were written and performed by ELO; the title track which closed side two featured Newton-John as lead vocalist. The Newton-John side also featured Cliff Richard, the Tubes and Gene Kelly. At the time of the album's release, Olivia Newton-John was signed to MCA Records, while ELO were signed to Jet Records. A compromise was worked out between the two companies in that the album was released on MCA in the US and Canada, and on Jet in the rest of the world.
