If you ever wondered what happened to Rydell High's favorite power couple, last seen in "Grease" nearly 35 years ago, Sandy and Danny (a/k/a Olivia Newton-John and John Travolta) may have aged but they've obviously kept singing and dancing through the years.

In this irresistibly charming holiday duet, the two superstar performers reunite and sing of such holiday traditions as coming home, watching "It's a Wonderful Life" and ... "makin' love all night"? Alrighty, then!

"Grease" fans in particular should get a kick out of the clip's clever nods to that iconic flick, in which the pair first sang such massive hits as "Summer Nights" and "You're the One That I Want." Their modern dance moves owe a bit more here to country line-dancing than '50s rock 'n' roll but the sweet reunion makes for fine holiday fun.

"I Think You Might Like It" is taken from This Christmas, a collection of holiday tunes recorded by the longtime friends, marking their first musical collaboration in three decades.
