Grateful Dead Music Forum

Can someone please help me understand why the grateful dead anthology has a g# in phils and Bobbies line? It happens in every bar of G. I understand G# is in the key of A, however we are playing mixo so it's flat. Also it's flat in em, a common substitute for g. Anyone have any idea?

It's a G natural in A mixo.

I don't have that book so I can't comment further, but I agree in that I don't think there should be a G# where you say there is.
