One more thing about Witchy Woman. I just remembered that not only the G minor chord in the verse contains the E note. The D7 chord does as well. If we were following "strict theory", we would say that in the key of G minor the 9th in the D7 chord should be an E flat - a D7b9 chord. I think one of you talked about it earlier in this thread. But I'm pretty sure this was one of the cases where the
instrument dictated what happened - not scales. If Bernie had been writing the song on piano, I'm pretty sure he wouldn't have added the E note on top of those chords. But he decided to try the open E string on top and thought it sounded cool.
