Im pretty sure this is 100% correct for the purpose of just singing along. The 
original doesnt have much guitar. The "Fx8" In the chorus sounds good if you play 
it right. It sounds like the "Hey hey hey hey hey hey hey" you hear in the 
original song. Rate please :) 

Capo:2(For original, works fine on capo 1 for those of you like me with a lower voice)

Verse:C,F,G,Am
Pre Chorus:F,G,F,F,G 
Chorus:C,Am,F
Chorus Ending:Am,G,F(x2)

 

C                        F
I set all my regrets on fire
          G                        Am
Cause I know I'll never take the time
C                           F                        
To unpack my missteps and call all of our friends
     G                          Am
I figure they would take your side
                              
(Pre Chorus)
            F                  G
I make the bed, just not that well 
                 F      
Your name comes up a lot
         F    
When I talk to my mom
         G
Oh, I think she can tell

(CHORUS)
        C
I was out on the town
      Am                        (F-F-Fx8 quick strums)  
So I came to your window last night
          C                         
I tried not to throw stones
        Am             (F-F-Fx8 quick strums) 
But I wanted to come inside
           C                       Am                  (F-F-Fx8quick strums)
Now I'm causing a scene, thinking you need a reason to smile
   Am    G           F
Oh no, what have I done?
          F        G       Am
There's no one to keep me warm
 
Verse:2

      C                      F
So maybe I should put up a fight
                 G                     Am
I'll call them back and borrow a box knife
    C                         F                             G           Am
So I can learn to live with all the stupid s*** I've been doing since '99
       
       C                     F
And I know I could be more clever
        G                     Am
And I know I could be more strong
         C                       F                        
But I'm waiting for the day you come back and say
        G                        Am
"Hey, maybe I should change my mind"

    F
I drink a lot
          F             G
I'm not sure if that's new
            F                          F   F   F
But these days when I wake up from a night I forgot
         G
I just wish that it never came true

CHORUS (2x)

        C
I was out on the town
      Am                        (F-F-Fx8 quick strums)  
So I came to your window last night
          C                         
I tried not to throw stones
        Am             (F-F-Fx8 quick strums) 
But I wanted to come inside
           C                       Am                  (F-F-Fx8quick strums)
Now I'm causing a scene, thinking you need a reason to smile
   Am    G           F
Oh no, what have I done?

          F        G       Am
There's no one to keep me warm

        C                    Am
And I know I could be more clever
        F                     G
And I know I could be more strong
        C                     Am
And I know I could be more clever
        F                     G
And I know I could be more clever

I knew there would come a day when all was said and done
(And I know I could be more clever)
Everything I was is everything but gone
(And I know I could be more strong)
All my big mistakes are bouncing off your wall
(And I know I could be more clever)
The bottles never break, the sorrow never comes
(And I know I could be more clever)
So come on let me in, I will be the sun
(And I know I could be more clever)
I will wake you up, I am who I was
(And I know I could be more strong)
Just open up your heart, open up your heart, open up your heart
(And I know I could be more clever
And I know I could be more)

I was out on the town
So I came to your window last night
I tried not to throw stones
But I wanted to come inside
Now I'm causing a scene, but you need a reason to smile
Oh no, what have I done?
There's no one to keep me warm
