. I would appreciate it. And while we're on the subject of keys, I have sort of noticed the F#, C# thing. I think the first chord of Two Heads is C#. Again, this makes me wonder exactly what the hell instrument Grace was using to write these things, because those are some REALLY annoying chords to finger (at least for me).
I just thought I'd add, yes, a lot of Paul's songs are in these keys, and so are Grace's. So it may well have something to do with Grace's voice as well - Marty doesn't write in these keys at all as far as I've seen, and Paul's songs are generally written much more with Grace in mind than Marty's, I think.
Also, the keys of G and D (at least as far as Grace's self-penned tunes) may have to do with her writing on piano (if she did, in fact, write on piano). Those are the two easiest keys to play in, next to C, of course.
