Princeton Station in Chelmsford has some now and again. In fact, they are having Steve Sweeney (now there's some old-school Bahstan comedy) in January. The new Nashua Center for the Arts opens in April and I'm hopeful we'll start getting something there. Finally, if you want to drive a bit, the Chevalier Theater in Medford square gets some acts and its much easier than going to downtown Boston. You can park for free and walk to a few places for dinner beforehand.
