Composer William Finn explains how he became involved in "The 25th Annual Putnam County Spelling Bee" and what drew him to the show's quirky characters; charts the development of the "Marvin" trilogy, including "March Of The Falsettos" and "Falsettoland", and talks about the differing approaches of James Lapine and Graciela Daniele to that material; tells the story of his own early-1990s medical crisis and how that became the basis for "A New Brain"; and recounts his extreme trepidation about the new revue of his songs, "Make Me A Song", during its debut in Connecticut. Original air date - December 1, 2006.
