In 1944 While the Australian Army battled Japanese troops in New Guinea and the Allied Nations continued the fight against Axis forces in Europe, a performance of German operatic works sung by Marjorie Lawrence was being cheered on at a remote army base in Australia’s Northern Territory. By 1946 Lawrence was singing the same German repertoire in Berlin to an audience of United States, Russian, French and British Generals accompanied by the Berlin Philharmonic. This dissertation aims to answer why an opera singer was chosen to entertain one of the biggest military audiences of World War II in Australia, why an Australian was chosen to sing at the highly diplomatic Berlin concert in 1946, why Lawrence was singing Wagner, Richard Strauss and other German composers’ works to Allied forces at all and on both occasions, why Lawrence sang the repertoire she did.
