This cassette was taped by the Rats of Tobruk Association. ABC war correspondent Chester Wilmot (1911-1954) pioneered the use of recording equipment in the field. He spent several months in Tobruk in 1941. In October 1941 the ABC Field Unit recorded a concert put on by 400 Australian soldiers in an ammunition cave. Wilmot’s introduction sets the scene and items feature individual and chorus items and a saxophone and piano accordion performance.This item is part of a collection of items owned by Arthur Lock, a member of the 2/23rd Battalion, an all-volunteer Second Australian Imperial Force which served as part of the garrison during the Siege of Tobruk, then at El Alamein, New Guinea and Borneo. It has particular local significance as the battalion was know as "Albury's Own" because a large majority of the battalion's initial intake of volunteers came from the Albury–Wodonga region. A cassette of the Tobruk Concert held in 1941 in the caves behind the lines in an armament cave in Tobruk. "TOBRUK CONCERT 1941"world war 11, rats of tobruk, tobruk, chester wilmot, concert in tobruk
