Thanks to Xaveir for the chords for this song,
All the rest of the work was figured out by ear, but I don't know if this is right.
Take this as a guideline to anyone who wants to play this.

  Dsus2 (Upstroke)
Flowers placed
        Am
At the foot of the grave
       G              Dsus2
Of the one we lost forever.


 Dsus2
Jesus, please,
         Am
Let her soul rest in peace
          G                    Dsus2
And make way a new angels in heaven.


       Dsus2      Am
Summergirl went away
       G             Dsus2
Everything has been dying.
       Dsus2      Am
Summergirl went away
         G            Dsus2
And the sun doesn't shine.


Dsus2
All alone
        Am
In the house we called home
         G                       Dsus2
And the walls still echo of her laughter.


       Dsus2
We'd dream of a world
      Am
Far away we'll never know,
           G                     Dsus2
Since she left I don't dream anymore.


       Dsus2      Am
Summergirl went away
       G             Dsus2
Everything has been dying
       Dsus2      Am
Summergirl went away
         G            Dsus2
And the sun doesn't shine
