Here's another song about the River Clyde.

I have no idea who wrote it. I learned it at Danny Kyle's festival pub in Edinburgh some years ago.
I've never come across it since

BANKS OF THE CLYDE
^^ (ch)
   There's grass now growin' where an empire stood
   Flowers on the banks o' the Clyde
   Tall trees stand now wi' their leafy boughs
   And there's salmon swimmin' in wi' the tide

A million men a million jobs,
Their hammers ringin' out in the dawn
And the cranes rose high tae the morning sky
Before all the work was gone
The shipyards lined the length o' the toon,
It's fame was known world-wide
For the finest boats on the seas afloat
Were stamped 'Made on the Clyde'

The shipyard barons turned the green tae black
With the sweat of the workers toil
They didn't give a damn that this pleasant land
Was a wealth that they shouldn't spoil
The fish in the river couldn't swim any more,
Pollution was the word that was used
But the blackened slums and the burnt oil drums
Showed a city that had been abused

Aye there she stood, a dear green place,
Before all the industry came,
Then a town of steel and the great pit-wheel,
The circle turns round again
For Glasgow now is a Greenpeace dream
That millions can enjoy
But amongst the hosts you'll find the shipyard ghosts,
The ranks of the unemployed
