Shakedown: I understand what you are saying, but what I am saying is that if you look in the books, the song is written in B major. I checked 2 different books, and it is written that way both times. I didn't "infer" that it was the key of B, it was right there in black and white. Your reference to the IV and the V I believe are correct, and why the song sounds good with the guitar played in E, but the song is written in B. If you want me to cite the books, I am happy to, but it will have to wait until tonight as I am at work right now and the books are at home.
What I don't agree with is your statement "so using B Ionian, although a major scale, is technically incorrect." A couple of things there: Firstly, if it is "technically incorrect, then the song was written incorrectly. Secondly, I don't see why this would be technically incorrect. If I wrote a song in the key of A major and have the rhythm based off of the A chord, would you say that was "technically incorrect"? If so, why? I could have based the rhythm off of D or E (and even with the rhythm based off of A, I am sure I would have some D and E chords in there somewhere), but I don't see why not doing so would be "technically incorrect". I can see how writing based off A chords would lack a "Jerry feel" to the song, but I don't think there would be anything technically incorrect about it.
OMD: I have played key of E to the FOTM midi, and it does sound good, well, as good as my slow and sloppy play will allow, but when I get going decent for a line or two I can tell it is nice. After looking up the key for FOTM, I haven't tried playing it in B (Ionian pattern starting on Fret 7 of String 6), but will try that tonight if guitar playing time is to be had.
As far as the other post, I think I get what you mean by "stacking thirds", which is just a terminology with which I was unfamiliar. I read over the other stuff on the chord families, I think I always understood the IV and the V. I think I now see the ii, iii, and vi. I think I need to think about the seventh diminished a little more though. Thanks for taking the time to post all that, I will refer back to what you and others have written as I work on it more.
Mama Mama many worlds I've come since I first left home.
