Olivia Newton-John on the 40th anniversary of XANADU International superstar Olivia Newton-John celebrates the 40th anniversary of XANADU, the movie musical that spawned mega-hit songs “Xanadu,” “Magic,” and “Suddenly.” Over the years, Olivia has acknowledged that the experience of shooting the film with the legendary Gene Kelly represents a huge moment in her career despite the problematic screenplay. Olivia sends her best to co-star Michael Beck, songwriters John Farrar and Jeff Lynne, choreographer Kenny Ortega and the fabulous dancers in the film including Broadway icon Sandahl Bergman (who I adore) and Teri Beckerman. Check out the first few seconds where the voice shows NO age whatsoever. What a great star, and such great songs.
