North Georgia Theatre at Piedmont College returns for a second season filled with summer comedies, beginning with “I Do, I Do!” at the Swanson Center in Demorest. “North Georgia Theatre is a professional repertory theater company at Piedmont that brings together actors, directors and designers from across the Southeast to produce theater in the Northeast Georgia mountains,” said Bill Gabelhausen, chairman of the college’s Department of Theatre. “I Do, I Do!” is a two-character musical that spans 50 years, from 1895 to 1945, focusing on the ups and downs experienced by Agnes and Michael Snow throughout their marriage.
