The theater group The Fabulists has returned for the season to the Tisbury Amphitheater at the Tashmoo Overlook, presented by the Martha’s Vineyard Playhouse. Every Saturday morning at 10 am through July and August, families can visit the amphitheater for a witty outdoor improvisational theater show aimed at children and join in the fun through audience participation. This Saturday’s show will be “Ashpet: an Appalachian Cinderella Story.” Tickets to the show are $10; $5 for children ages 2 and up. Visit mvplayhouse.org for more information.
