I won't be much help on these, but in the spirit of "something is better than nothing" . . .

I can give you the intro: Capo fret 3 and play F - C - G. Unusual song structure. My guess is that it's in the key of Bb if that's of any use to you.

This live acoustic version is in the key of G. I can give you the chorus:
(C)Wanderers ... have (G)gone ... (Am)chieftans ... (C)will ... (G)rain ... (D)birds
(Am)who ... (G)to speak ... (C)seasons ... (Em)ravens ... (D)crows ... (C)soak ... (C)skies
The verse centers around Em.
Anyway, that's all I got. Good luck.
