Well I know I've got it somewhere on a corries LP... Anyway, I've managed to find a short clip of the tune on the internet and these chords seem fit along with it:

(E)I'll sing (A)you this (E)October song,
oh, there (B7)is no song be(E)fore it.
The words and (A)tune are none of my (E)own,
for my (B7)joys and sorrows (E)bore it.
Beside the (E???)sea. The brambly (E)briars
in the (B7) still of (E)evening,
birds fly (A)out behind the (E)sun,
and (B7)with them I'll be (E)leaving.

E??? - Play an open E but instead of the G# on the 3rd string, move up a fret to the A. Atlleast that sounds right to me. I'm not very good at picking those sort of things out.
