Xanadu boasts a book by Little Dog Laughed playwright Douglas Carter Beane and utilizes songs from John Farrar and Jeff Lynne's film soundtrack. The musical, according to press notes, "tells the story of one of the nine muses of ancient Greece who comes to earth to inspire the greatest of artistic achievements – a roller disco. Along the way she falls in love, bumps into an old acquaintance and for the first time, feels the desire to create herself." The 1980 film "Xanadu" was written by Richard Christian Danus and Marc Reid Rubel and was directed by Robert Greenwald. Described as "a fantasy, a musical, a place where dreams come true," the film starred Olivia Newton-John, Gene Kelly, Michael Beck, James Sloyan, Dimitra Arliss, Katie Hanley, Fred McCarren and Ren Woods. Jeff Lynne and John Farrar composed the film's score.

The Helen Hayes Theatre is located in Manhattan at 240 West 44th Street.
