Olivia Newton-John and John Travolta Reunited in Their Sandy and Danny Grease Costumes

Grease was the word in 1978—and it's still going strong in 2019.

On Friday (December 13), the famous movie-musical stars, Olivia Newton-John and John Travolta, reprised their iconic roles as Sandy and Danny in honor of a Meet n’ Grease sing-along event at the Coral Sky Amphitheater in West Palm Beach, Florida. Not only did Newton-John and Travolta attend the event, but they dressed as their famous characters for the first time since the film. "First time in costume since we made the movie! So excited!!," Newton-John penned on Instagram.

In the pic she's wearing a version of her good-girl Sandy look including the swingy pale yellow skirt, white blouse, and ’50s-style yellow cardigan sweater. Travolta, 65, is in full T-Bird mode in a leather jacket, of course.

Travolta also shared the shot on his Instagram, along with video clips of the massive crowd enjoying the show. There's even a moment backstage when you can hear him say, "Holy shit! This is my first experience." His final photo is a picture of him and Newton-John in the red convertible, just like the parting shot of the movie—well, without the flying part.

According to People, Newton-John, 71, also changed into Sandy's iconic black leggings and leather jacket later on in the evening.

The two are scheduled to make a couple more appearances at similar events over the weekend. The Grease reunion comes in the same week that the actual leather jacket Sandy wore in the final scenes of the movie was gifted back to the actor. She had previously put it up for auction to benefit the Olivia Newton-John Cancer Wellness and Research Center, but the (anonymous by choice) generous donor who bought it for $243,000 thought it belonged with Newton-John herself. “The odds of beating a recurring cancer using the newest emerging therapies is 1,000-fold greater than someone appearing out of the blue, buying your most famous and cherished icon, and returning it to you, which is what I’m going to do right now,” the man said, according to People.

“This jacket belongs to you and the collective soul of those who love you. Those for whom you are the soundtrack of their lives. It should not sit in a billionaire’s closet for country club bragging rights. For this reason, I humbly and respectfully return it to its rightful owner, which is you."

The jacket will be on permanent display at the Australia-based research institute—but here's hoping Netwon-John takes it for one last electrifying spin alongside Danny Zuko.
