The matter of which you're made of

 I am made of utopia and melancholy 

Dreams, sorrow, grief and hope

I am made of a heart of gold

and rust and I am now so old

I am made of chess and care

I am made of caress and despair 

Sometimes I am made of love

Sometimes of absolute freight 

Sometimes peace like a white dove

Sometimes killing I just might

I am made of flesh and silver

Blood and tears, a believer 

Sometimes again I am

Sometimes again I'm not
