Glad you posted to Anders. So now, I would like to speculate what he may come back with on E minor and G.
E minor blues. And Rock n Roll "G".
Let's see how off base I am in his line of thinking.
And yup, old and enjoying the experience of learning guitar. I've been at it for a few years now Mark and take my wins when I can get them. I learned my 1st song by ear lately and thought that would never happen. It's a simple song - Simple Man by Charlie Daniels and only uses 3 chords, E D & A, but after trying to "tune" my ears to hear what I was listening to for years, I was over the moon to get this one down.
Good luck with your progress.

This year the diet is definitely gonna stick!
