We have two very fine versions of this classic Austrailian in the DT. Here is bawdy parody.
Road to Gundagai
Tune: Road to Gundagai
There's a crack winding back,
From her belly to her back,
On the road to Gundagai
There's a yank there beside her,
You bet your balls he'll ride her,
Beneath the starry sky
With a frenchie on his big prick,
He'll ride her with ease
As he scratches up the gravel
With both of his knees,
Though the time will come to pass,
When he'll whop it up her arse,
On the road to Gundagai.
