Brett Cahoon, band leader of Good Shot Judy, channels early 1960s Frank Sinatra as he strolls through a packed audience at Deltaville Maritime Museum’s waterfront park during a July 24, 2021 concert. He stops to sing “Happy Birthday” to Chelsea Graver of Gloucester, who turned 30 that day. He then dances with her. Good Shot Judy is set to perform 6:30-9:30 p.m. Friday, March 25 at Flat Iron Crossroads, 7709 Flat Iron Road, Gloucester. (Photo by Don Richeson)
