Ben Fetsch as Tevye and Ashley Smith as Golde, seen here in dress rehearsal, star in Sacred Heart High School’s production of Fiddler on the Roof, which runs this weekend. Three evening shows are scheduled for 7 p.m. Thursday, Friday and Saturday with a matinee at 2 p.m. on Sunday. Tickets are $15 and available at Sacred Heart, Louck’s Pharmacy and M&M Meats. Fiddler on the Roof, the story of a poor Russian Jewish milkman whose faith is challenged by changing times and his five strong-willed daughters, is one of the best-loved and most successful musicals of all-time.
