Em          G                D Dsus4 D Dsus4 D
Maybe the rain's holding off,
Em          G                   D Dsus4 D Dsus4 D (I'll just refer 
Surely it knows, we're down here                   to this as  
                                                  D riff now)
Em             G            D riff
Walking 'round barefoot lost
Em                                      
Pretty soon these clouds have got to clear
G              D        
I know it's a lot
G                   D       
Arousing thunder I only ask it to stop
G               D        
For a second so I could coax you to talk
  
  (There could be a very quick G in here, I'm not sure)  
Em  ^  D riff

Em             G              D riff
Think when we first layed eyes
        Em                        G                       D riff
Didn't know who you were and then I was one more passerby
             Em                      G                    D riff
You were the girl in the entryway, thats all that I knew but
          Em                              
You were still in school and I was insecure
G              D    
I know it's a lot
G                D                           
Arousing thunder I only ask it to stop
G               D                   
For a second so I could coax you to talk
      F#m      F#m F#m F#m    F#m  F#m   D riff  D riff 
About your dreams and orange soda tea leaves, tv,  more....more
(If you don't like all the changes above you can just strum the F#m 
the whole way though til 'more' but it doesn't sound as good)
Em               G              D riff
Looks like the rains holding off
Em              G           D riff
Might as well take this slow
         Em                            G                      D riff
You know sometimes when I hold you in silence I listen real close
Em                              
Then I hear you talking to my soul

G                       D  
Well I know it ain't half 
G                   D   
of this story I'm only meaning to ask
G                   D                        D riff  D riff D riff etc
Just what would it take to coax you to laugh? To laugh,   To laugh To laugh

Em  G  D riff
Em  G  D riff
Em  G  D riff
Just play G over the following lines

What would it
What would it               D
What would it take you to laugh?

Repeat the above twice, then

I'm not too sure on the ending but I'll give it a go
G           Em
Ba ba ba ba ba ba ba ba
G           Em
Ba ba ba ba ba ba ba
G           Em       D
Na na na na na na na

Then play D (plus the riff a few times) till
the end.

A couple of the chords:
