Just watched Kathy Mattea sing this on You Tube. Clearly she is in some alternate tuning. I suspect Jeremiah Mc Caw above is about on the right track. My problem is I am lazy, I don't read music. I need to know the chord shapes she is using and the chord they represent. I suspect alinact above has the right idea chord-wise. I have tried googling for chords for Ready for the Storm, but no one seems to be addressing the obvious open tuning. Can anyone out there help me?
