The music in the film was derived from the actual score transcripts used in the P.O.W camps which survived World War II.
The film is based on the diaries, reminisces and testimonies of Helen Colijn and Betty Jeffrey as described in their books, "Song of Survival" and "White Coolies".
In 1982, the Peninsula Women's Chorus performed a tribute concert to the women in Australia recreating a concert from the surviving score transcripts.
From her memory, in the actual P.O.W camp, Margaret Dryburgh wrote down and arranged the music for the vocal orchestra from works by the likes of such composers as Ludwig van Beethoven, Frédéric Chopin and Claude Debussy.
Filmed in sequence.
