Hi again everyone,
I've been traveling to Santa Fe NM so I missed a day of checking this thread. Thanks for the moral support jj

.
Just one thing: I'm going to have stick to my guns here and respectfully disagree with Ron. As I've said already, I often find myself hearing things that aren't in the books.
The notes of the chords in question are:
Em9 - E G B F#
Bm flat 6 - B D F# G
What I hear - B F# G B
- B F# G C#
- E B F# G B
As you can see the chords are closely related. Emin9 will work, but it won't sound exactly like what's on the recording.
As for the variations in what i hear, they are partly measure dependent and partly verse dependent.
Anyway, the fingerings I suggest in the post above should sound right if you try them out.
Best, Tim
