The "Grease" co-stars reteamed last year to work on "This Christmas", a collection of covers and new tracks, and Travolta said that they want to add a few new songs to their body of work each year, reported E! online.
"We're going to try to add a couple of songs every year to that CD. And then maybe do a music video each year so, at the end of it all, we'll have a whole (collection). (We want to act in something) Maybe connected to the Christmas idea...," Travolta said.
Travolta's wife Kelly Preston's 12-year-old daughter Ella and two-year-old son Benjamin are following in his musical footsteps.
"My kids are musically inclined. Of course, my son is two so it hasn't developed yet, but my daughter has lots of interests in musical instruments and she's a good singer."
