Version 1:

Waltzing Matilda
Who bloody killed 'er
Laid her in the grass
With a shovel up her arse

Version 2:

Waltzing Matilda
Who fuckin' killed her?
Lying in the grass with a bullet up her arse
And his balls must be sore
Coz he caught them on the roll-a-door
Who'll come a waltzing Matilda with me?

Version 3:

Waltzing Matilda,
Who bloody killed her,
Lying in the grass with a dagger up her arse,
Along comes granny, and shoves it up her fanny,
Who'll come a waltzing Matilda with me?
