If only I could be less blind
If only I knew what to find
Everywhere and all of the time
It's bending my mind

Confusion's prince is at my door
The crown I wear is the one he wore
He's here to bring me down some more
And bend my mind

The friendly stranger calls my name
He only wants me for his game
But it don't matter, just the same
I'll bend his mind

I've waved my flags into the sun
I've fought my wars and now they're won
And I didn't need nobody's gun
I bent their mind

If only I could be less blind
If only I knew what to find
Everywhere and all of the time
It's bending my mind
