Capo2!
The whole song is actually quite simple. It's just variations of the C chord with 
the pull-off technique and picking of the strings. ;)

Intro: C  Csus4 C Am C (Rob picks at the high and low strings with his fingers 
during the first C and Csus4. He starts to strum and gradually pick up the pace at 
the Am. Listen to the full song for the strumming pattern)

C                                                Csus4
And their eyes were on a double string and their hands lay  
softly on the street now  
C                                      Csus4                                 
And I do believe that honestly that I know this is where I want to be right
C
 now
C                                         Csus4
There are pictures in her eyes, they?re a thread up for the skies 
C (remove 3rd finger)
So I wait 
C
Now with our souls misunderstood
Csus4
And our minds they saw a map of a way
C (Pull-off technique is used here. Pull-off fingers 1, 2 and 3. Listen to the song.)
For how long. 
For how long, how long must you take.
                                   C (Strum with 2nd finger removed)
I was set for that mistake but you moved. 
C                                               Csus4
And when there was nothing then that I couldn?t take
C
Its all on you, darlin?
C
You took me when my eyes were turned
C (Start to pick at the strings again here)
Its all on you, baby
C                                    Csus4(?)
You turned your back when I tried to learn
C 
Still I cannot lift my eyes
C (Strum with 1st finger removed)
If your hands are turning mine
C (Strum with 3rd finger removed)
But you dared not 
C                                     Csus4
What you said our souls could contain
Am
They could contain 
C (Pull-off 1st and 2nd finger a bit)
But now I?m gone
C                     
With a broken twisted soul in mind
Csus4 or Am (Whatever you think suits)
But for how long?
C
Cause I?ve wasted this train of youth all on you, all on you
C (Strum/pick while pulling-off the 1st, 2nd and 3rd fingers throughout)
It?s all on you 
It?s all on you
It?s all on you 
It?s all on you
It?s all on you 
(The line below is sung quietly and strummed/picked slowly)
It?s all on you
C (Strum full chord once)
