John Travolta and his leading lady, singer-turned-thespian Olivia Newton-John, reprised their Grease characters, Danny and Sandy, for a sing-along event in Florida on Friday. The two went all out, donning their old clothes — she in good girl yellows, he in bad boy leather. Newton-John posted an image on her Instagram account, pointing out it was the first time they’d been in costume since they filmed it 40-plus years back. It wasn’t, of course, the last time they saw each other: The two reunited, in 1983, for the angel rom-com Two of a Kind, which did not achieve the same success as Grease (though it did outperform Grease 2). As per Entertainment Weekly, the pair joined fans in singing along to songs like “Hopelessly Devoted to You,” “Sandy,” and “Greased Lightning.” The event, held in West Palm Beach, was the first of three “Meet n’ Grease” events, which moved to Tampa and then Jacksonville throughout the weekend.
