This "I was a POW in a Japanese camp" memoir was a little bit different from the rest.
The author doesn't dwell on the horrors so much as describe the singing, concert and theatre parties. In the hospital camps after the Burma-Siam railway was built, recovering POW's put on full performances of classical music, nightclub entertainment, comedian acts and full plays. They used mosquito netting, bamboo, palm leaves and anything they could to build a stage with lights, curtains and props, as will as kitting out the actors in costumes and wigs. The Japanese officers in charge of the camps got front row seats. Astonishing? The trick was to slyly make fun if their captors without them catching on. If they did, harsh beatings and punishments would follow.
I found a link to an online PDF book with more about it.
