There are four picking patterns used throughout the song. One for each of
the Am , Em  and C  chords used, with a change of pattern on the Am  in the
second and subsequent verses (although the original pattern is still used
for the choruses and outro). Its hard to tell what the fingerpicked
guitar does when the chords change in the outro, as there is another
guitar over the top, playing some similar ideas up an octave (I might get
round to transcribing these one day!)

Here is the chord structure for the song:
Note that the complete picking pattern takes up two bars.

Em  and C  picking patterns as first verse Am , butthe appropriate chord
shapes formed (Standard Em  and C ) using the same descending notes on the
B string.
Watch out for cramps playing this one, as you have to hold
thatopen Am  shape for a hell of a long time. Its best played on an
electroacoustic, with just a hint of reverb.

Am 
Rows of houses, all bearing down on me
I can feel their blue hands touching me
Em 
All these things into position,
All these things we'll one day swallow whole
Am  (4 bars)
    C    Em  Am 
And fade out again
    C    E*m  Am 
And fade out again
    C   Em     Am 
Ohhhhhh Ohhhhh Ohhhhh
    C   Em 
Ohhhhhh Ohhhhh
*First chorus ends here.
Third chorus as above, but with a double length "Ohhhhh" section.
