Seth Rudetsky is a one-man band of Broadway history and musicology, inside info, and pure love of the art form. A performer, writer, and musician, his over-the-top ebullience is always a shot of adrenalin. And everyone wants to talk to Seth. Rudetsky and his husband, the actor and producer James Wesley, are creators of the twice-daily talk show Stars in the House. And I do mean stars—twinkly-bright and quite famous. So tune in and get your Broadway chops up to snuff. —L.J.
