The Broadway musical Xanadu has its final performance on Broadway this afternoon. Based on the flop film musical starring Olivia Newton-John, Broadway's Xanadu featured Kerry Butler as a Greek muse and Cheyenne Jackson as the artist who she inspired. The Tony-nominated show, featuring a slew of memorable pop songs, played over 500 performances at the Helen Hayes Theatre before having its final performance on Broadway today. Xanadu is expected to have a production in London soon.
