Madness

7:30 p.m. Jim Motavalli will interview John Sedgwick, author of the book In His Blood (HarperCollins) about six generations of madness in a prominent WASP family. The host comes from a similar family of Early American nuts, so it should be a lively discussion. Technorati tags: WPKN, WPKM, Bridgeport, New London, radio, Montauk
