One such event that’s touring the country is the Meet ‘N’ Grease Movie Sing-A-Long, where original films stars John Travolta and Olivia Newton-John host special screenings of the 1978 musical with a Q&A session and VIP meet and greets.
(Don’t expect Travolta or Newton-John to show up on that one, it’s expected to be set in the 1950s with a new group of teenagers.)
Later in the event (via People), Newton-John also switched to a Sandy-as-a-T-Bird costume.
The description from Facebook says “all audience members (from General Admission to VIP Package ticket holders) are encouraged to come dressed as your favorite character from Grease.”
