Danny Zuko and Sandy Olsen ride again—literally. John Travolta and Olivia Newton-John, who memorably lit up movie screens in Grease, reteam for a holiday-themed video for "I Think You Might Like It," which shows the pair revisiting some dance moves from the 1978 musical. The single is from the recently-released holiday album This Christmas, which also features contributions from Barbra Streisand and Tony Bennett. All proceeds from sales will benefit the Olivia Newton-John Cancer and Wellness Centre and the Jett Travolta Foundation. Watch the video below.
