Waltzing Matilda, first lyrics were written 1895 in Australia, the title is not related to a dance and not related to a woman. Matilda was the name for a bag on the back of wandering shepherds. The lyrics are related to a sheep-shearer, who was a protester vs bad working conditions. During the protest a barn was burned, some sheep were killed. The protester Samuel Hoffmeister was accused, but he said he was not guilty and made suicide beneath his favorite water hole – where he usually ate some stolen sheep.
