“Ramblin” Dan Stevens, a veteran bluesman and raconteur is gonna CLOSE DOWN Darien Library when he talks, sings and plays in his educational and entertaining multi-media presentation on the history of the blue on Wednesday night. It’s true. The library has announced it will not be open for anything else after 7 p.m., Wednesday. If you’re not there to hear and see Dan Stevens, you’re not welcome. Go back the next day.
