They had some of the best chemistry ever seen in a musical, and now John Travolta and Olivia Newton-John are returning together to release a festive album out in time for Christmas. Starring opposite each other in the now legendary film Grease, the pair became worldwide stars off the back of it and in their track You're The One That I Want released the best-selling duet in history.

ABC reports that the idea to get together and record from songs came from the memory of the success of that song. "From the moment we decided to do this, magic happened. Everyone we contacted agreed to do it" said Travolta in a statement. "It just fell into place," said Newton-John. "With our busy schedules, I don't know how we got it done. John and I have always connected. That's never gone away. When we're together, we have a good laugh and feel bonded to one another. We've been through some amazing experiences together."

The disc will also contain guest appearances from Barbra Streisand, Tony Bennett, James Taylor, Kenny G, Cliff Richard and jazz legend Chick Corea. All songs will be Christmas staples bar one, a new one called I Think You Might Like It written by Jay Farrar who wrote the pair's famous hit. Speaking about their concept for the disc, Travolta said, "I wanted people to be able to play it around the house or in the car during the holidays, and make us part of your celebration. Gathering around house listening to Christmas music has always been an important part of that time of the year to my family."
