Through 15 years together, musician Sean McCann along with his wife and co-author, Andrea Aragon, have seen ups and downs most marriages would face. However, for Sean, his hard-drinking lifestyle started to spiral out of control and it threatened his career, life and marriage. Now sober for almost a decade, the former singer with Great Big Sea shares what he went through in a new book called "One Good Reason: A Memoir of Addiction and Recovery, Music and Love." Andrea writes about her side of the marriage and what the whole family sacrificed to remain intact. The book ends up tackling issues around addiction and sobriety, fame and religion, and reshaping life as they know it. Russell spoke with Sean and Andrea, as well as listening to two of Sean's songs, "Rise and Fall," and his newest single, "Set Me Free." [Note: This is an extended version of the radio broadcast.]
