Sandy & Danny from “Grease” are back together! Actually Olivia Newton-John and John Travolta are getting ready for the winter. The “Grease” stars released their holiday album “This Christmas” Now the cd This Christmas doesn’t just star the voices of Travolta and Newton-John, who look like they’re enjoying a cup of cocoa by a Christmas tree as they open presents on the album’s cover. Even more shockingly, Barbra Streisand, Tony Bennett, James Taylor, and Kenny G also make appearances on the 13-song collection on such classics as “Rockin’ Around the Christmas Tree,” “I’ll Be Home For Christmas,” and “Deck the Halls.” And there’s a special track for “Grease” fans: “I Think You Might Like It,” a sequel to “You’re the One That I Want.” I saw a clip of them On “Ellen” talking about their time together while filming “Grease”.
