Giorgio Moroder
"Blood From A Stone"

Circles of the human chain
Turning for the wheels of gain
A system with a power of its own
To draw blood from a stone

Every hour like the last
Tomorrow like the day just passed
Bearing down upon the flesh and bone
To draw blood from a stone

Cold machines that never stop
Even if a man should drop
Mercy never lets her face be shown
They draw blood from a stone
