THE STAGE

The only play playing around Harvard this weekend is Richard Brinsley Sheridan's The Rivals, at the Loeb--it's getting a good production, by all accounts, so if you like Restoration comedy (there's no accounting for tastes) it's probably all right. Which is probably more than you can say for some of the other things around...Bertolt Brecht's In the Jungle of Cities is mostly just incomprehensible (369 Performance Center, near Union Square in Somerville), Changes is evidently mostly just improvisatory (Theater Two, near Kendall Square), and vacation is evidently, mercifully, unbelievably, mostly just imminent, and high time too.
