Nearly 40 years after its release, 1978’s Grease is still the word. This weekend, the Alexander Film Society presents a special Grease Sing-Along at the Drive-In. Cloverdale’s fairgrounds turn into a retro-party with your favorite Pink Ladies and T-Birds on the big screen, and everyone is invited to sing and dance along with classic hits like “Summer Nights” and “Greased Lightnin’.” You won’t be branded a fool. Food and drinks will be available and proceeds go to the film society. Gates open at 6:30pm on Saturday, April 30, at the Cloverdale Citrus Fairgrounds, 1 Citrus Drive, Cloverdale. $15 per individual; $50 per car. avfilmsociety.org.
