Guys, gals, tourists, and Dins alike were greeted with a pleasant pelvic-thrusting, slicked-hair sporting, and tight-pants wearing surprise this Thursday afternoon.

GREASE the Harvard student musical gave a teaser performance this afternoon featuring the entire GREASE cast. They serenaded and scintillated the massive crowd with favorites “Summer Nights” and “Grease Lightning.”

Senior Tali Friedman (“Sandy”) and freshman Ben Moss (“Danny”) embodied the sweet and innocent good girl and suave softie-inside tough guy that made this a classic story of boy re-meets girl for the ages.

And if this preview was any indication, this musical’s gearing to be one hell of a good time.

Enjoy!

PS -- You know the saying “lightning never strikes twice?” False. You’ll be able to catch the performance again today on the Science Center lawn @ 12 pm.
