When your first single from GREASE, the biggest movie musical of all time, is the chart-topping "You're the One That I Want," and it becomes the best-selling duet in pop music history - that's a tough act to follow. Almost 35 years later, John Travolta and Olivia Newton-John have combined their iconic voices for THIS CHRISTMAS, a newly recorded album featuring Christmas favorites with guest artists such as Barbra Streisand, Tony Bennett, and James Taylor! Travolta and Newton-John will donate the artist proceeds from the album equally to their respective charities, the Jett Travolta Foundation and the Olivia Newton-John Cancer and Wellness Centre in Melbourne, Australia.
