At the intro, she just plays loud, distorted pick scrapes, then:

G-------------------------
D-------------------------
A-------------------------
E---3---3-3-3--3-3--3-3-3-  etc. etc. etc.

That goes thru the intro and verse, then for the "Betting on the
bull in the heather part", play this right at the start:

G--12-- (harmonic)
D------
A------
E------

The bass is silent for the next bit, then enters on a 
G note before the repeat of the intro. Verse/Chorus/Intro/out.
