My Conversation With Barry Manilow and Bruce Sussman: Collaborative 'Harmony'

Tonight on PBS, I have a conversation with longtime musical collaborators Barry Manilow and Bruce Sussman. The Grammy-winning songwriters have been partners for more than 40 years, with projects that include the song and the musical "Copacabana," and the song "Let Freedom Ring," for the televised bicentennial celebration of the U.S. Constitution. Their latest project is the musical Harmony, based on a real-life German singing group that battled to stay together (and live) as the Nazis ascended to power in 1930s Germany.

In the clip below, Sussman discusses the quest for harmony as represented in their new musical.
