WARWICK-Beginning Saturday, Jan. 25, the local improvisation theater troupe, Jabberwalk, will be performing at the Tuscan Café on South Street in the Village of Warwick. "We have a great new show with some old favorites, and plenty of opportunity for the audience to join in the fun," said Donna Haley, director of Warwick's MCC Actor Training School. The audience is invited to participate in each show. "Speak with your favorite expert, hear leading political figures, pop stars, your man on the street, see objects that speak and a Broadway musical," she said. "It's lots of fun." Tickets are $5 and can be picked up in advance at the Tuscan Cafe. Seating is limited.
