In 1980 Jeff Lynne was asked to write for the soundtrack of the musical film "Xanadu" and provided half of the songs, with the other half written by John Farrar and performed by the film's star Olivia Newton-John. The movie performed poorly at the box office, but the soundtrack did exceptionally well, eventually going double platinum. The album spawned hit singles from both Newton-John ("Magic", a no. 1 hit in the United States, and "Suddenly" with Cliff Richard) and ELO ("I'm Alive", which went gold, "All Over the World" and "Don't Walk Away"). The title track, performed by both Newton-John and ELO, is ELO's only song to top the singles chart in the United Kingdom. More than a quarter of a century later, "Xanadu", a Broadway musical based on the film, opened on 10 July 2007 at the Helen Hayes Theatre to uniformly good reviews. It received four Tony Award nominations. The musical received its UK premiere in London in October 2015. Casey Kasem called The Electric Light Orchestra a "seven-man supergroup" and "amazing" for hitting The Top 40 a remarkable six times in a one-year period from August 1979 to August 1980 before playing "All Over the World" at #23.
