“It takes a village” is the proverb about raising a child but the same holds true in producing a community theatre production. That is certainly the case with the Sterling Community Theatre Troupe’s production of the musical comedy whodunit, Curtains, which will be presented at 8 p.m. next Friday and Saturday, July 5 and 6. and at 3 p.m. on Sunday, July 7, in the Sterling High School Theatre.With 24 cast members, well over 100 costumes, 18 musical numbers, a band of six and eight scene changes, Curtains is not a small show by any stretch of the imagination. “In many ways this has to be the biggest summer show we’ve done in many years,” says Dennis Dutton, director of the show.
