This one got into my head a few days ago for some reason, so I transcribed it. Please feel free to suggest any corrections!

Lost Mine of the Chisos
Bill Staines

There is a tale of the Big Ben country
And I heard it once, so long ago
By firelight, on the Rio Grande
When the moon shone bright on Mexico

An aged one, an old compadre
Told this to me, as I to you
The desert sun had burned his body
But his eyes told me the tale was true

Years ago, up in the Chisos
Conquistadores, they mined for gold
And far below, they built a prison
It was a bold Presidio

Early each and every morning
The Spaniards led unto the hills
Blindfolded slaves, a captive people
To work the mine and do their will

Do do do do do do… (to tune)

The years they fade, like dying echos
The way is lost, the trail is gone
All that remains is just a legend
A story in a passing song

But if you stand at San Vicente
And watch the sun on Easter morn
Where its first light falls on the mountains
The way is shown, and the secret torn

And listen well upon the West Wind
The sound of horses will fill the air
Don't venture on, they guard the treasure
From anyone who ventures there

Do do do do do do… (to tune)

There is a tale of the Big Ben country
And I heard it once, so long ago
By firelight, on the Rio Grande
When the moon shone bright on Mexico

Do do do do do do… (to tune)
