Heya Katie...
Well, Catie has never published her own chords or tabs for any of her songs...and I've actually heard her say she had no plans to ever do so either. It was Roger True who transcribed them...and he hasn't done that for a long time. Therefore, we don't have anything for pretty much since MSLGOY. His transcriptions were from the piano and weren't always the "easy" guitar chords...but if you can play guitar, you can probably figure most of them out...I know she uses a lot of capo!
The only place I know of to get chords from earlier is what I call the
"stealth site". Mark K used to have clips of boots available for download. He took all the music off a long time ago because of storage issues...but he's left up everything else.
If anyone out there can transcribe...or watch at a concert and notate...please share!

I don't play that well...and she really messes me up with the ocassional alternate tuning! She doesn't do that as much as other musicians though...again, capos are your friend!

Good luck!
