Don’t miss the Arrow Rock Lyceum Theatre’s production of “Souvenir,” based on the story of New York socialite Florence Foster Jenkins. Jenkins once said, “People may say I can’t sing, but no one can ever say I didn’t sing.” Though this wealthy eccentric couldn’t produce two consecutive notes in tune, an improbable fandom flocked to see her as she performed her Carnegie Hall concert that famously sold out in two hours. This charming comedy reminds us that you can achieve anything when you set your mind to it. 8 p.m. with 2 p.m. matinee.
