G   Cadd9 G Am   D


G              Cadd9                      Em7       Cadd9
Katie you're a brave girl, and I know its only just started.

          G           Cadd9        Em7        Cadd9
I'm gonna be there at 6, with some flowers on sticks

          G                              D
That were clipped just to make the weak strong.

    G            Cadd9                            Em7        Cadd9
And Katie, its a strange world when girls can get so broken hearted

           G          Cadd9     Em7         Cadd9          G      D
If it were me and the universe, I'd get the worst of this gone.

G      Cadd9     G          Am
Katie, Katie I'm sorry that in your condition

    D                           G
The sunshine's been missing but Katie,

      Cadd9           G         Am    D
Don't believe that it isn't there.

       G      Cadd9    G
Oh and Katie, Katie be happy

     Am                     D
This world can be ugly, but isn't it beautiful?

      G                Cadd9           G            Am       D
We're not really here,       and we're really not there

                     
We're really not there.




           G Cadd9    Em7 Cadd9

G              Cadd9                     Em7            Cadd9
Katie you're a brave girl and courage is something I'll need now.

                  G         Cadd9          Em7      Cadd9
'Cause its been a hell of a day I've spent fading away

   G                      D
We all fade sometimes, I believe

    G           Cadd9                        Em7         Cadd9
And Katie its a strange world as I watch our tables get turned around

                   G                   Cadd9
And you've got the strength that I've lost

            Em7             Cadd9     G     D
Who'd have thought you'd be carrying me?

    G      Cadd9     G           Am
And Katie, Katie I'm sorry that in your condition

     D                           G
The sunshine's been missing but Katie,

      Cadd9           G       Am           D
Don't believe that it isn't there.

       G      Cadd9    G
Oh and Katie, Katie be happy

      Am                     D
This world can be ugly, but isn't it beautiful?

          G           Cadd9          G            Am   
We're not really here,       and i'm really not there

And it's not the end of the world,

             G           Cadd9
It's not the end of the world,

              G           Cadd9
It's not the end of the world,

           G             Cadd9           D
'Cause the cops wouldn't break up this party.

    G      Cadd9     G          Am
And Katie, Katie I'm sorry that in your condition

     D                          G
The sunshine's been missing but lately,

      Cadd9           G        Am        D
Don't believe that it isn't there, yeah  yeah.

       G      Cadd9    G 
Oh and Katie, Katie be happy

      Am                     D
This world can be ugly, but isn't it beautiful?

      G                Cadd9           G           Am        D
We're not really here,       and we're really not there.

             G                Cadd9
I said we're not really here,

          G            Am
And we're really not there.


We're really not there.
