Olivia Newton-John and John Travolta recreate iconic Grease looks for the first time since 1978

Olivia Newton-John and John Travolta have returned as Danny Zuko and Sandy Olsson more than 40 years since their Grease debut.

On Friday, the duo recreated the outfits worn by the iconic characters in the hit film to the “Meet n’ Grease” sing-along event at the Coral Sky Amphitheatre in West Palm Beach, Florida.

In a behind-the-scenes photo shared by Newton-John on Instagram, the actor can be seen wearing her “good Sandy” outfit consisting of a yellow cardigan, matching skirt and flat shoes, while her former co-star sported Zuko’s iconic quiff hairstyle with an all-black ensemble complete with a leather jacket.

“First time in costume since we made the movie,” Newton-John captioned the image. “So excited!!”

Travolta also shared photos and videos from the night on his own account, telling fans: “#Grease is still the word. Opening night of #MeetNGrease at the @coralskyamp in West Palm Beach!”

Later in the evening, Newton-John changed into her character’s “bad girl” outfit which featured a cropped leather jacket and black leggings.

The reunion comes one month after Newton-John auctioned off the famous leather jacket she wore during the Grease finale to raise funds for the Olivia Newton-John Cancer Wellness and Research Centre.

While the jacket was purchased for $243,200 (£185,000), it was recently returned to the star to put on permanent display at the research institute.

“The odds of beating a recurring cancer using the newest emerging therapies is a thousand-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 entrepreneur who bought the jacket told Newton-John.

“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.”

The man, who wished to remain anonymous, continued: “For this reason, I humbly and respectfully return it to its rightful owner, which is you.

“Godspeed for a quick recovery.”

Newton-John founded the ONJ Cancer Centre during her first battle with the disease in 1992.

The singer is currently battling cancer for the third time, having been diagnosed with stage four breast cancer in 2017.

She said in August that she has chosen not to know how long she has left to live, explaining: “If you believe the statistics, you’re going to make them happen. If somebody tells you, ‘you have six months to live’, very possibly you will – because you believe that.”
