CAPO ON SIX OR SEVEN!!!
(it sounds fine on either, just see which suits your vocal range best.
It does sound good on lower frets too.) 

These chords are a somewhat easier to sing cover for the video version of
Joni performing Woodstock live on BBC in 1970...it's very easy to find on
the internet and a great performance. 

I tried and tried to find some of these chord names with chordbook, but when
i searched the chord names it gave me it came up with differnet finger
placements...so here is a chord chart and I'm sorry if the names don't match
properly!

Em
I came upon a child of God
       D                 Dsus4
He was walking along the road
  D                         Dsus4
I asked him, where are you going?
            Em
And this he told me
Em
I'm going down to Yasgur's Farm,
       D                      Dsus4
Gonna join in a rock and roll band.

     D              Dsus4            Em
Get camp out on the land and get my soul free.

Em   Cadd9   A7Sus4/E         G Cmaj7/E 
We are  stardust,     we are   golden,

       Em                               Dsus4 D  Asus4/E  G  Em
And we got to get ourselves back to the ga---aa--aa------ar-den.



Em
So can I walk beside you?
       D                   Dsus4
I've come here to lose the smog,
   D            Dsus4             Em
I feel to be  a cog in something turning.
Em
Maybe it's just the time of year,
D                      Dsus4
Maybe it's the time of man.
         D         Dsus4                 Em
I don't know who I am,  but life is for learning.


Em   Cadd9   A7Sus4/E         G Cmaj7/E 
We are  stardust,     we are   golden,

       Em                               Dsus4 D  Asus4/E  G  Em
And we got to get ourselves back to the ga---aa--aa------ar-den.


Em
By the time we got to Woodstock,
        D              Dsus4
We were half a million strong

        D                Dsus4         Em
And Everywhere there was song and celebration.


And I dreamed I saw the bombers

          D          Dsus4
Riding shotgun in the sky,
        D          Dsus4
Turning into butterflies
          Em
Above our nation.

Em   Cadd9 A7Sus4/E   Em       
We are stardust,      billion year old carbon,
      G Cmaj7/E 
we are golden

Em
Caught in a devils bargain

Em     Cadd9      Asus4/E               Dsus4 D  Asus4/E  G  Em
And we got to get ourselves back to the ga---aa--aa------ar-den.
