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".
The camp in this movie is not a P.O.W. camp because the inmates are not prisoners of war. It is an internment camp, where civilians are kept for no other reason than being of the wrong nationality. This happened, for instance, to Japanese civilians in the U.S. The AANS nurses were entitled to be treated as POW but the Japanese did not believe they were military.
In 1982, the Peninsula Women's Chorus performed a tribute concert to the women in Australia recreating a concert from the surviving score transcripts.
Filmed in sequence.
