Martin illuminates the sacrifice, discipline, and originality that made him an icon and informs his work to this day. To be this good, to perform so frequently, was isolating and lonely. It took Martin decades to reconnect with his parents and sister, and he tells that story with great tenderness. Martin also paints a portrait of his times-the era of free love and protests against the war in Vietnam, the heady irreverence of The Smothers Brothers Comedy Hour in the late sixties, and the transformative new voice of Saturday Night Live in the seventies.
