"Grease," has posted a declaration in tribute to the overdue singer.

"My dearest Olivia, you made all of our lives a lot better," the actor wrote on Instagram. "Your effect was incredible. i really like you so much."

Newton-John and Travolta gained worldwide repute while in 1978 once they starred as bad boy Danny and sweet Sandy inside the movie musical "Grease."

only some years in the past, the pair revisited their roles for one special night in West Palm seashore, Florida when they attended a sing-alongside of the film and a Q&A consultation on the Coral Sky Amphitheatre.

Newton-John wore her signature yellow skirt and matching cardigan, complete with the white button up. Travolta wore a conventional leather jacket, along with his hair slicked lower back.

It was the primary time the 2 had been in costume on the grounds that they first made the movie more than 40 years in the past, Newton-John wrote on Instagram at the time.

In his tribute, Travolta delivered, "we are able to see you down the road and we will all be collectively once more."

He signed it: "Yours from the instant I noticed you and all the time! Your Danny, your John."
