CAMDEN — The air-conditioned Camden Opera House, 29 Elm St., hits high summer in stride with an original musical comedy benefit the last weekend of July; and free outdoor Sunday concerts in August.

The opera house is co-presenting “Bingo Queen,” a joyous fun show by John Burstein to benefit for Knox County Meals on Wheels, 7:30 p.m. Friday and Saturday, July 29 and 30. In addition to being entertained (and voting on the title character), theatergoers get to play a game or two themselves – and win prizes from sponsors Camden Harbour Inn, Natalie’s Restaurant and Maine Sport Outfitters.

The “Bingo Queen” cast, directed by Chris Clavelli with choreography by Cyndi Clayton, features Maine-based performers Burstein and Joel Crowley; and New York actors Heather Petruzelli, Lauren Assume, Nick Curley and Madelyn Monaghan. Tickets are $20 in advance, $25 day-of-show, via camdenoperahouse.com or 236-3154; doors and box office open 7 p.m. both nights.

For the third straight summer, Camden Summer Sounds will offer free outdoor concerts at the Camden Snow Bowl: jazz with Novel Jazz and the Denny Breau Trio, Aug. 7; blues with Mark “Guitar” Miller Band and the Blind Albert Duo, Aug. 14; bluegrass and country with Breakin’ Strings and Travis James Humphrey, Aug. 21; and folk with Gordon Bok and Jud Caswell, Aug. 28. All shows begin 4 p.m., and concertgoers are encouraged to bring lawn seating and picnics. Camden Summer Sounds is sponsored by First National Bank and First National Wealth Management, the Town of Camden, and the opera house’s Community Arts Fund. Rain location will be Camden Opera House. Information on all events can be found at camdenoperahouse.com.
