Song Sung Blue follows the alternately inspiring and tragic love story of Lightning & Thunder, a homegrown Milwaukee husband and wife singing duo that pay tribute to the music of Neil Diamond. The film goes backstage into the personal lives of this brave couple – from their humble beginnings over 20 years ago to the threshold of fame, from disaster to rebirth through to the most dramatic chapters in the lives of these authentic American dreamers. It’s about the uniquely American ability to invent one’s self and strive for a seemingly impossible goal. It’s about fleeting celebrity and love and about a couple who manages to maintain their passion for one another amid the vicissitudes of life.
