Coiled

"The lunatic is in my head
The lunatic is in my head
You raise the blade, you make the change
You re-arrange me 'till I'm sane
You lock the door
And throw away the key
There's someone in my head but it's not me.
And if the cloud bursts, thunder in your ear
You shout and no one seems to hear
And if the band you're in starts playing different tunes
I'll see you on the dark side of the moon"
