Singing along to Grease, the musical that will not die, is a guilty pleasure ย— no one admits they do it, but everyone does. If youย’re ready to come out of the Grease loverย’s closet, you can belt out ย“Summer Nights,ย” ย“Greased Lightinย’ย” and ย“Youย’re the One I Wantย” at the River Oaks Theatreย’s sing-along screening today.

Donย’t worry, you wonย’t be alone. The 1978 film musical about love and cliques at fictional Rydell High School during the 1950s has become a cultural icon. It made movie stars out of Olivia Newton-John as good girl Sandy Dumbrowski and John Travolta as bad boy Danny Zuko, gathering legions of fans along the way. 11:55 p.m. today and tomorrow. 2009 West Gray.
