Grease stars John Travolta and Olivia Newton-John are going to make some beautiful music together.

Thistime it's for a Christmas album, and they plan to include 13 gueststars. Among them: Barbra Streisand, Tony Bennett, James Taylor, ChickCorea and Kenny G.

The idea for the collection came from Travoltaafter he received a holiday season text from Newton-John noting thattheir 1978 smash, You're the One That I Want, had just become thebest-selling duet in pop music history. "From the moment we decided todo this, magic happened," says Travolta. "Everyone we contacted agreedto do it."

Adds Newton-John in the release, "With our busy schedules, I don'tknow how we got it done. John and I have always connected. That's nevergone away. When we're together, we have a good laugh and feel bonded toone another. We've been through some amazing experiences together."

In addition to stars singing more classic seasonal fare, one of the highlights of the album is the one original song, I Think You Might Like It, a sequel to the Grease smash You're the One That I Want. It's a new tune by that song's writer/producer John Farrar.

"My desire was to make This Christmasan intimate album, not something too ostentatious or showy," saysTravolta. "I wanted people to be able to play it around the house or inthe car during the holidays, and make us part of your celebration."

Travoltaand Newton-John will donate the artist proceeds from the album equallyto the Jett Travolta Foundation, to combat children's disabilities,including autism and seizures, and the Olivia Newton-John Cancer andWellness Centre in Melbourne, Australia.

This Christmas will be available Nov. 13 from Universal Music Enterprises.
