If you love the music and costumes of the 1920s, you’ll love “The Boy Friend,” to be performed at Bay High School March 21, 22 and 23. Catchy tunes and period dancing, as well as the typical comedic mix-ups that come with false identities, make for a light-hearted, flapper-era adventure. General admission is $7; reserve seating is $10. Tickets available at the door or by emailing email@example.com. Cast list can be found at www.bayvillageschools.com/TheBoyfriend.
