Hi, thanks a lot for all the comments.
@ Wolfgang: there are a couple more than just 6 LPs/CDs. Bogle's first audio recordings come from the late sixties, and he never seems to get tired -I really hope so ;)

Here are the words of the song 'The Heart of the Land' (recapitulated by the comments above and, of course, the singing of Eric):

*************************************
THE HEART OF THE LAND
[Eric Bogle]

Well, the long day has ended with its toil and its sweat.
He sits on the verandah in the fading sunset
And has a cold beer as the light dies away,
For a hard working man the best time of the day.

He's the heart of the land, this tired dusty man,
Though he'd laugh if you said so, claim to be nothin' grand,
Just a battler survivin' as best as he can,
But this land's in his heart and he's the heart of this land.

And he thinks of the day and the work that's been done,
And of tomorrow, the toils still to come.
He'll be up and working before the sunrise.
Here on the farm you don't work nine to five.

He's the heart of the land, this tired dusty man,
Though he'd laugh if you said so, claim to be nothin' grand,
Just a battler survivin' as best as he can,
But this land's in his heart and he's the heart of this land.

Now he's seen some hard times but he got by somehow,
And he's been through too much to give it up now,
Though he's not one for wearin' his heart on his sleeve
He know he'd rather died, than pack up and leave.

He's the heart of the land, this tired dusty man,
Though he'd laugh if you said so, claim to be nothin' grand,
Just a battler survivin' as best as he can,
But this land's in his heart and he's the heart of this land.

For this is his country by blood and by birth.
To him there's no finer place on this earth,
And though pastures of plenty he might never see,
He knows where he is and where he wants to be.

He's the heart of the land, this tired dusty man,
Though he'd laugh if you said so, claim to be nothin' grand,
Just a battler survivin' as best as he can,
But this land's in his heart and he's the heart of this land.

Yes he's the heart of the land, this tired dusty man,
Though he'd laugh if you said so, claim to be nothin' grand,
Just a battler survivin' as best as he can,
But this land's in his heart and he's the heart of this land.
Yes this land's in his heart and he's the heart of this land.
