A sing-along version of the movie musical "Grease" will be screened at the Levitt Pavilion on Monday, July 18, sponsored by the non-profit group try to establish a movie theater downtown.

The 1978 classic starring John Travolta and Olivia Newton-John will be shown at 8:30 p.m., following a live, pre-movie music program at 7:30.

The film has subtitles with song lyrics, so if moviegoers know the tunes, they'll have help on the words to sing along, said Sandra Lefkowitz of the Westport Cinema Initiative.

Admission is free, but the group is raising money to establish a non-profit movie house in Westport and will be accepting donations at the show.

The live warm-up program at 7:30 will feature a performance by young cast members of the Music Theatre of Connecticut's production of Disney's "Aladdin Junior Edition." Selections from the Academy Award-winning score will include "A Whole New World" and "Friends Like Me," the Cinema Initiative said.

Also performing will be KinkSlip, a four-piece band that includes three Staples High School graduates. The band plays rock, R&B, Motown, oldies and other styles, show organizers said.

In addition to singing along with the "Grease" songs, Lefkowitz said, filmgoers will be free to dance, too. They also can have their pictures taken with cardboard cutouts of Travolta and Newton-John outfitted in their roles as greaser Danny Zucko and "good girl" Sandra Olsen.

Filmgoers may bring their own snacks or buy them at the pavilion. Rain date is July 25.

The Westport Cinema Initiative, a registered non-profit organization, has launched a drive to raise $4 million to open a two-screen movie theater downtown. The group is considering three sites.
