I remember the expression 'tinny', and I grew up in country New South Wales. It was one of those wonderful words with a wealth of meanings - tinny sound (meaning scratchy as though sounding from far away), lucky (Helen's original question), the little aluminium boat. The beer connection came later I think; beer came in bottles first in my memory, then later in steel cans.

Expressions that I knew from childhood were regional, when I moved to Sydney in 1970 nobody here had heard of them!
