Em - 022000
Am - x02210

It basically goes:

C       Em      Am
I don't need to know,

        C              Em              Am
Why the oceans blue or how the flowers grow.

C       Em       Am
I don't need to live,

        C             Em                Am      C
Waiting on someone to forgive me for my sins.

        Em            Am
Like my father before me,

      C          Em          Am
I'm a working man, a working man.

    C       Em      Am
But I don't need to believe,

       C                    Em      Am
In the something that won't save my sanity.

NOTE: When you hear a slight variation whilst Dallas is strumming the Am chord it is this:

|-0-0-0-0-|       (On the 4th repetition): |-0-0-0-0-|
|-1-1-1-1-|                                |-1-1-1-1-|
|-2-2-2-2-|                                |-2-2-2-0-|
|-2-2-0-2-| x4                             |-2-2-0-2-| (Basically just merge it into the 
C)
|-0-0-0-0-|                                |-0-0-0-3-|
|-x-x-x-x-|                                |-x-x-x-x-|

Key:
x = Mute or Don't play that string.

(Chorus)

The chorus is incredibly easy all you need is:

G - 320033
Am - x02210

NOTE: After the last Am you play during the verse you basically strum x00000 twice 
the first word in the chorus (No) then play the G chord. (If you can reach it you can play an 
or you can just go straight into the G if you want)

But the chorus is just:

   G
No I don't need I don't need to know, no,

                Am
I don't need to know oh, oh, oh, oh.

                G
I don't need to know oh, oh, oh, oh, oh, oh,

                Am
I don't need to know oh, oh, oh, oh, oh.

How easy is that!

(Verse 2)

The second verse is the same as the the first pretty much the same 3 chords in the same pattern:

C - x32010
Em - 022000
Am -  x02210

It goes:

C       Em      Am
I don't want to live,

     C           Em                Am
In a world where faces change from day to day.

    C       Em              Am
And I don't want my life to be,

C          Em        Am       C
So full of doubt and misery.

              Em             Am
The years now pass without a trace.

     C                  Em          Am
It's something that I'm learning to embrace.

    C        Em               Am
How most bad nights are spent awake.

         C           Em            Am
Thinking about how I don't want to live that way.


(Chorus)

   G
No I don't want I don't want to live, no,

                Am
I don't want to li e, e, ea, e, ive.

                G
I don't want to li e, e, e, ea, e, ive,

                Am
I don't want to li e, e, e, ea, ive.

(Verse 3)

For the most part the same as the other verses except for the last line:

C       Em                 Am
I don't know but I've been told,

            C                  Em              Am
That if you don't believe, the devil owns your soul.

        C           Em             Am
Well if this is the truth, then to hell I'll go.

     C       Em      C
'Cos I don't need to know.
