You don't have to get on a train to encounter great performances this weekend. The Church of St. Joseph production of T.S. Eliot's Murder in the Cathedral is in its final weekend, with performances at 7:30pm Thursday-Saturday and a final show Sunday at 2pm. I reviewed their show a couple of weeks ago, but forget about me, the New York Times loved it! Suffice to say you don't want to miss this unique, site-specific performance (and it only costs $10! $5 if you go in a group of 4 or more!).
