k so im trying to play constellations by jack johnson i can do the intro and solo but my only problem is i can not for the life of me find the chords needed to play anything else. im learning the song out of the book so its right. Its an absolutly amazing acoustic song and not to hard but it doesnt say how to play the flippin chords in the book lol. so yeah here it all is.

Drop C tuning

and the chords i need to know how to finger are C(b5)sus2, Csus2, C6/9 so if anybody could help me that would be excelent.
