I concur about Waltzing Matilda. It may be more appropriate for the NZ Rugby team supporters to sing about a person who likes kidnapping sheep.
I firmly believe that all 5 and 6 year olds should be taught the words to "Khe Sanh" and/or "Am I Ever Gonna See Your Face Again" at primary school. Lets get the stadia rocking.
I believe Khe Sanh is very popular with Dingo -
"So I looked across the country from end to end
I tried to find a fly-half to settle in, whom my mixed up plans could mend
I had anyone do the ol'gig, a-flyin' Beale when I could
But the nightlife nearly drove him round the bend
And I travelled round the land from year to year
And each one found me winless, one more year the worse for wear
And I've been back to Brisvegas, you know the answer sure ain't there
But I'm driftin' to New South Wales to check things out again-ain
Well the last player out of Sydney's already in
And only seven flyn' hours, they'll be landin' from Hong Kong
And there ain't nothin' like the misses from a jaded defence
I'n gonna get them to hit the corners all night long
Well the last player out of Sydney's already in"
