The Martha’s Vineyard Regional High School production of “Chicago: The Musical” drew crowds of Islanders out of the cold and into the audience at the Performing Arts Center this weekend for three nearly sold-out shows. The musical, which was organized with plenty of help from MVRHS staff and the Island community, starred a cast of 60 MVRHS students, including Penelope Dutton as Roxie Hart, Darby Patterson as Velma Kelly, Ben Nadelstein as Amos Hart, Jared Livingston as Billy Flynn, Aidee Espino as Matron “Mama” Morton, and Michaela Piche as Mary Sunshine.
