Repeat riff one throughout (there is no guitar slash
at the start of this verse)

Middle eight:
The middle eight is in two sections:
Here you play the chords:

I think we've lost our perception... etc.

second time you play G - flick the rhythm/treble switch very quickly.

Then play this riff x6 during the indechipherable spoken part.

Note: 5th time the there is a pinch harmonic (?)on the
      7th fret instead of a Bm chord.

Then play Riff 1 x 4 and repeat the chorus

Coda:
Riff 1 is played around 20 times then after about 15
times a rhythm guitar comes in playing Bm G G/F#
and the riff dissapears in the mix and then drops out.
Before coming back along with the rhythm guitar and it's continued until 
the song ends on Bm.
