The quick changes from C to Em can be played as a walk-down from the normal C form 
to this chord: E A D G B e
               x 2 0 0 1 0

Intro:
[finger-picked] Am - C - Am - C
[strummed] G - Dm - C - Em - Am (x3) (hammering-on/pulling-off the third fret of 
the Low E string with your pinky for the bass groove)

F?r any [ Am ] time I felt like [ C ] punching out.
Any- [ Am ] -one who passed as [ C ] I fell down. 
F?r any [ Am ] time I've wondered [ Dm ] how much pain can I endure [ G ]
without letting all the [ C ] blood [ Em ] flow [ Am ] out.

F?r any [ Am ] time I've tried to [ C ] hold her hand, 
just to [ Am ] watch her move a- [ C ] -way.
F?r all those [ Am ] nights I would drink until I 
[ Dm ] found the guts to speak 
And then [ G ] threw them up all [ C ] o- [ Em ] -ver the [ Am ] place. 

Can I just [ Dm ] say how worth the [ C ] wait [ G ] it's [ Am ] been.
Can I just [ Dm ] say that I would [ C ] do [ G ] this [ Am ] again.
Because [ Dm ] now I know what happens in the [ G ] end
is that maybe I would leave them all [ Am ] instead. 

F?r any [ Am ] time I've looked in- [ C ] -side myself 
and seen a [ Am ] big, black void of [ C ] emptiness.
F?r all those [ Am ] nights I outline my [ Dm ] life passions 
to [ G ] wish that I was [ C ] me- [ Em ] -mory [ Am ] less. 

Can I just [ Dm ] say how worth the [ C ] wait [ G ] it's [ Am ] been.
Can I just [ Dm ] say that I would [ C ] do [ G ] this [ Am ] again.
Because [ Dm ] now I know what happens in the [ G ] end
So maybe I would burn them all [ Am ] instead. 

And now you [ C ] say, [ G ] say, [ Dm ] say 
would you just [ Dm ] stay, [ G ] stay, [ Am ] stay.
There is a [ Dm ] point to all this, there's a point to me.
There's a [ F ] home I have made in your heart as it beats
And [ Em ] to its rhythm [ F ] I will [ G ] sing 

D? do [ C ] do [ G ] do [ Dm ] do, do do [ Dm ] do [ G ] do [ Am ] do.
D? do [ C ] do [ G ] do [ Dm ] do, do do [ Dm ] do [ Em ] do [ Am ] do.

Can I just [ Dm ] say how worth the [ C ] wait [ G ] it's [ Am ] been.
Can I just [ Dm ] say that I would [ C ] do [ G ] this [ Am ] again.
Because [ Dm ] now I know I have you in the [ G ] end
So maybe I would burn them all [ Am ] instead.
