Look inside and you will see
The words are cutting deep inside my brain
Oh they're burning, quickly turning
Knife of words is driving me insane
Insane
Yeah, yeah

Raven black is on my track
Please show me how to neutralise the knife
Show to me in surgery
The art of fighting words to conquer life
Conquer life
Yeah, yeah

Ooh baby, I can rock and roll
Ooh baby, get out of my soul
Now the wicked lance of fear
Driven from my heady mouth and brain
Crash course in brain surgery
Has stopped the bloody knife of love again
Yeah, yeah, yeah
