Seriously, if you're in your 20s and 30s and still don't know all the words to the songs (and the dialogue, for that matter) in the iconic movie musical, Grease, then I'm afraid that I'll need more proof that you haven't been living under a rock. You still have a few hours to clear your evening schedules for a dusk showing of the film at Dolores Park, the first of the San Francisco Neighborhood Theater Foundation's Film Night in the Park series. Bundle up, bring a picnic dinner, and get ready to sing at the top of your lungs. I'm especially looking forward to John Travolta's pelvic thrusts in "Grease Lightning" and Olivia Newton-John's pitch-perfect rendition of "Hopelessly Devoted" (also a karaoke standby for me). Guess mine is not the first heart broken...
