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!
