"Xanadu" is the title song from the soundtrack of the 1980 musical film of the same name. Written by Jeff Lynne of the English rock band Electric Light Orchestra (ELO), the song is performed by British and Australian singer, songwriter and actress Olivia Newton-John, with Lynne adding parenthetic vocals in the style of his other songs on the Xanadu soundtrack, and ELO providing the instrumentation. It was Lynne's least favourite of his own songs.
