‘Grease’ Singalong

You aren’t supposed to talk in a movie theater, much less sing. But the sponsors of this event will make an exception. Older children who may have encountered “Grease” through a school production can experience the whole musical in this 1978 film, and sing along to every number. The lyrics will be shown on the screen during the movie, which stars John Travolta and Olivia Newton-John as a sizzling couple in a crowd of 1950s teenagers. Memorable tunes include “Hopelessly Devoted to You,” “You’re the One That I Want” and, appropriately, “Summer Nights.”
