SONG SUNG BLUE is a documentary feature film that tells the alternately inspiring and tragic love story of Lightning & Thunder, a homegrown Milwaukee husband and wife singing duo who pay tribute to the music of Neil Diamond. Filmmaker Greg Kohs goes backstage into the personal lives with 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.
