There is no better setting in Vermont to see a summer show, according to Seven Days theater critic Elisabeth Crean. Barn owner, producer and actor Peter Boynton “blends Broadway talent with Vermont vets and greener gems into a smashing cast,” Crean effuses. “The result? The best musical theater in Vermont.” Catch Boynton’s “Broadway Cabaret” on Sunday nights in July; Always... Patsy Cline runs for two weeks in August.
