The English translation of a traditional miners poem from the Ruhr area:
Glückauf! GoodLuck! The words you hear from all,
Who stand by us down in the mine;
It speaks of loyalty and standing tall
Also in the worst of time.
Glückauf! The song that everyone sings,
Who with us hand in hand
The black gold to the surface brings
For the good of the fatherland.
Glückauf! You hear it all around
In shafts dark and deep.
St Barbara protect, do safe us keep
From the Tommy knockers cracking sound.
Glückauf! Be it also your last hello,
When you take your leave
On that road we all must go,
The one that gives nobody real reprieve.
