Chord help needed

Hey guys,
Would any of you be able to help me identify the chords that Randy Stonehill is playing here in the first song of this interview, especially the parts higher up on the neck, but the others as well. Thanks for any help!!

Just looks/sounds like 2-note partials, e.g., 7th fret E, 8th fret B up to 8th/10th and 10th/12th, back down. Kind of G-C6-G, but with whatever open strings he's adding in - good right hand there.

Beginning: G, Em, A, Cadd9, D. Then, some 2-not chords - guessing it's E and B strings, 7th fret (both strings), 5th fret, then 3rd/4th frets, basically G-D-G.

He plays his G chords with 4th finger G on the E string to make the switch to C easier. The partials I described at the start come later.

Thanks! I appreciate you taking the time to help!
