The Jumpin’ Juba trio will provide the live music at the Medford Council on Aging’s frightfully fun Halloween Party at the Senior Center. Members Steve Hurl (guitar and vocals), Bruce Ward (keys) and Brian Flan (drums) mix regional styles of blues from Chicago, Memphis and New Orleans together with rootsy rock ‘n’ roll. The luncheon menu will be pasta, meatballs, salad and desserts. Wear a costume — a prize will be awarded for the best one! Tickets are $3 per person (limit two); purchase at the Senior Center information desk beginning on October 4. Supported in part by a grant from the Medford Arts Council.
