40 years later, Grease is still the word!

John Travolta and Olivia Newton-John reunited this weekend to celebrate their iconic 1978 movie musical, hosting the first of three "Meet 'N' Grease" singalong events in Florida. The pair were dressed in their Rydell High best on Friday in West Palm Beach, with Newton-John rocking Sandy's "good girl" outfit, a yellow cardigan and skirt, and Travolta in his T-Bird black leather.

"#Grease is still the word," Travolta captioned a slideshow of the pair greeting fans, posing in their infamous red convertible and thrilling the crowd as they walked onstage together during the sing-along event. "Opening night of #MeetNGrease at the @coralskyamp in West Palm Beach!"

Newton-John, who changed into a "Bad Sandy" leather jacket later in the evening, also shared a shot with Travolta, writing, "First time in costume since we made the movie ! So excited!!"

The "Meet 'N' Grease" events will be held in Tampa on Saturday and Jacksonville on Sunday, with Travolta promising additional appearances by the T-Birds and Grease director Randal Kleiser.

ET spoke with Newton-John back in October to discuss the over 500 items of Grease memorabilia that she was putting up for auction to benefit the cancer treatment center bearing her name in Australia. While poring over the items, the actress revealed some little-known facts about the film, including that she had to be literally sewn into the black pants in the film's finale, following Sandy's transformation, because the zipper was broken.

"They had to stitch me into them when I had to shoot," she says while showing off the infamous wardrobe the item at Julien's Auctions in Beverly Hills, California. "The zipper's still broken, but they're fabulous. They're just gorgeous."

Another item up for auction was Newton-John's own Pink Lady jacket. As fans of the film know, Sandy was never inducted into the film's girl gang, but when production wrapped, they made Newton-John an honorary member and presented her with her own jacket, which is even embroidered with her character's name.

"I wanted to be a Pink Lady, I wanted to be accepted by them," she said of her character in the film "But, of course, I wasn't a part of the team in the end. So, the crew, at the end of filming, presented me with my own Pink Lady jacket, so I'd feel part of it."
