Helen Colijn (1920-2006) was held captive in a Japanese prison camp on the island of Sumatra for three and one half years during World War II.  One remarkable survival mechanism for some of the prisoners at the Women’s Barracks Camp in Palembang was making music, and a series of concerts was prepared and given in which the women sang a cappella arrangements of great works of Western Art music.  The music was arranged by Margaret Dryburgh and Norah Chambers. Programs included Dvorak’s Largo from the New World Symphony, the Pastoral from Handel’s Messiah, Chopin’s ‘Raindrop’ Prelude, and Tchaikovsky’s Andante Cantabile, among many other works.
