Stage

Lost and Found: It’s been musical chairs--and directors and actors--at the Matrix Theatre, where Saturday night’s opening of Constance Congdon’s much-anticipated “Tales of the Lost Formicans” was postponed for the second time. Gone with the elaborate set and rear-screen projection effects are actress Bette Ford and director Michael Arabian. K Callan is in for Ford, Kristoffer Siegel-Tabori and Lee Shallat are the new directors. The opening has been re-scheduled for Sunday.
