Last night Olivia Newton-John appeared onstage at the Melbourne premiere of Xanadu the Musical to sing the legendary song with star Christie Whelan and the cast.
Now her former Grease co-star John Travolta has indicated he will step back in time, by agreeing to appear in a reunion for 70s sitcom Welcome Back, Kotter.
It will be the 35th anniversary of the show that ignited his movie career.
The ‘sweathog reunion’ is part of the TV Land Awards in April.
So far Lawrence Hilton-Jacobs (Freddie “Boom-Boom” Washington), Ron Palillo (Arnold Horseshack) and Marcia Strassman (Mrs. Kotter) have also confirmed.
But Robert Hegyes (Epstein) and Gabe Kaplan (Mr. Kotter) are yet to lock in. Maybe now Travolta is on board they will be more agreeable.
The event will also feature Family Ties and The Cosby Show cast reunions.
