VERSE 1-------------------------------------

C             Bb5
Lay down your injured arms

Am                F
Cos we've come so far as one

C      Bb5         Am              F
Dig me out of here so on my back I feel some sun

C                Bb5
Flee the darkness of this hour

Am                F
Leave the modern world behind

C           Bb5
My life's a burning tower

Am                F    bend to     G
The walls are the hills we climb

CHORUS-----------------------------------

C                    F                 Am
How do I fight these inconceivable odds

                 F
From bringing me down?

C                  F                  Am
The drive for explanation grips us all

                   F
And pins us to the ground

C         F                  Am
If I ever leave your side unattended

               F
Exposed to the fall

C         F                   Am
If I ever leave your heart undefended

                 F
Your back to the wall

BRIDGE---------------------------

C F C F

VERSE 2 (Same as verse 1)--------

Everyone must exist alone
we all run races with no ending
my thoughts are synchronised
to a clock with no time
The hearts of men will be corrupted
Abandoned by themselves
Life makes their minds destructive
frightened by the trigger inside

CHORUS---------------------------

OUTRO (Fade out the BRIDGE)
