Theodoros Giorgos Andronicos and friends, Sydney April 1901

Theo is seated at the front of the picture. At the time he was 20 years old. The names of his companions are not known, but it is thought that they were fellow musicians, a bouzouki and a mandolin player. Theo played the violin. What was the occasion - they are dressed in suits, with sprigs of daphne in their button holes?
