Casimir Pulaski Day Chords

The second tab for this song is correct for one of the guitar parts, but here's a
version with the lyrics. The song sounds OK with just the chords.
I think there are two guitars and maybe a harp, so this is by definition incomplete.

Capo: 1st fret

MAIN RIFF:
     D        C                Am   G
     v ^ v ^       v^       v^       v^
e|---2-2-2-3-------33-------00-------33--------------------------|
b|---3-3-3-1-------11-------11-------33--------------------------|
g|-2-2-2-2-0-------00-------22-------00--------------------------|

Intro: Main Riff 2X

D                 C
Goldenrod and the 4H stone, 
    Am
the things I brought you, 
       G                               D  C  Am G
when I found out you had cancer of the bone 

D                        C
Your father cried on the telephone, 
       Am                     G
and he drove his car into the navy yard, 
        D                  C   Am  G
just to prove that he was sorry 

       D                    C
In the morning, through the window shade, 
         Am                            G
when the light pressed up against your shoulder blade, 
        D                           C  Am G
I could see what you were reading.
