From memory.

In Walaroo its mighty fine
In mounta and kadeena
And they remind me of the time
When first i was a streamer
but when at night my eylids close
my mind to far off places goes
The Southern cross its soft light glows
But shining down on Sennon

Now underground its all the same
As Crofty or Sellegan
The dust the dark the flickering flame
It might just be Illogen
The same old songs are heard again
The tunes the tales the family names
The stars hear nightingales refrains
When shining down on Sennon

Now Xmas is the bravest time
we'll sup a pint of tawney
And fiddler Jim will lead the mine
When we sing trelawney
We've sung it all the world around
Where tin and copper may be found
The very stars will hear the sound
When shining down on Sennon

At home the mining gates have closed
Or so says last years letter
Old Redruth town is in bad straights
And poole it is no better
But in my mind I see thm still
As if I'm climbing
Cambourne hill
And high above the stars will still
be shining down on Sennon

Now South Australia's been real good
To cousins Jack and jenny
And many a Cornish lad would say
He's earned a pretty penny
But Jacky this and Jacky that
This cousin Jack would eat his hat
To see the stars that even yet
Are shining down on Sennon.

I have sung it in St Agnes with that village instead of sennon
It fits most of the locations better anyway.
