Wot chune is that, rich-joy? We sing "more beer" to "Amazing Grace" around these parts.

While the Shiny Bums don't have a song to the tune of "Advance Australia Fair" (as far as I know), they do have their Rugby song, to the tune of "I Am Australian"

"We are large, but we are stupid
And from all the rugby lands we come
With leather balls, and silly headgear
I am, youse are, we are the rugby ones."

I particularly like the Sensitive New Age Cowpersons' version of the National Anthem, with everything thrown in and muddled up -

"Waltzing Matilda, in there and fight,
With Skippy the bush kangaroo,
Skippy, true blue.
God save our queen." etc etc

Speaking of Campbell the Swaggie, haven't seen him for a while...
