I've a question concerning the weird but good sounding chords Pete Doherty plays when he jams. The chords he uses in his famous songs are mostly simple ones and you can look them up on ultimate-guitar but when he jams (in documentaries and so) he uses ones that sound quite "old fashioned" but not very jazzy (or is it the intervals he uses). I hope anybody can help me on that...

i'm also a bit of a peter doherty fan
and other than standard E, A's etc. i've noticed that he uses alot of C#m, B etc. particularly higher up the fret board.
the best thing to do is to see what chords he uses most reguarly in most songs.

Hope that helps.
