Yes - thanks for the explanation. I forgot that you can switch keys in the same song.

The part of learning the songs is most pertinent. I was too involved with the music theory and without the practice (learning the songs) it seems so mathematical. I was missing the application of the theory.

You've made this point often in your posts but I'm just now getting it!

I know all of the songs you mention; and now that I play them back in my head I think I have the feel for the minor key (not just an academic exercise!)

Heard two songs today on the old-fashioned FM radio: Fleetwood Mac's 'Gold Dust Woman' and The Allman Bros. 'In Memory of Elizabeth Reed'- are those minor key.?
