Motorhead

Murder I am, you know it was me
I was the one, that you didn't see
I was the cut, down to your bone
I put you there under that stone
I, I am the blade, I am the dream of the brave
I, I am the knife, I bring grief to your life
I, I am the sword, I am the word of the Lord
Do what you will, I bring you the edge
I am the one to sever your head
I cut so deep, I can cut straight
All depends on the moves you make
I, I am the blade, I am the promise unmade
