This is repeated (softly) until about :
G———————————————————————————————————|
D———————————————————————————————————|
A———————————————————————————————————|
D——0—0—5—0h3—3h2——0—0—5—0h3—3—2—————|

Here is the fast part! Comes in at :
G—————————————————————————————————————————————|
D—2h3h5—————————————————2h3h5—————————————————|
A——————0h2h3—3—x—x———————————0h2h3—3—x—x——————|
D———————————————————3—0———————————————————3—0—|

That is the main riff of the song. There are, however, variations:
At :                              Before the band goes silent:     
G——————————————————————|  G—————————————————————————|
D—3h2h0————————————————|   D—————————————————————————|
A——————0h2h3—3—x—x—————|  A—3—3—x—x—x—3—x—3—x—x—3—3—|
D——————————————————3—0—|  D—————————————————————————|

After the instruments go silent for a bit, you can just
repeat the original riff, only still more softly until 
the fadeout:
G———————————————————————————————————|
D———————————————————————————————————|
A———————————————————————————————————|
D——0—0—5—0h3—3h2——0—0—5—0h3—3—2—————|

*Just as a side note, I'm aware that Colin plays this song a bit
differently live. When Thom starts to sing "I used to think that..."
he begins a tiny improvisation on the D—string:
G———————————————————————————————————|
D———————————————————————————————————|
A———————————————————————————————————|
D—0——12—0—10—0—10—10—12—10—0————————|
You can play it like that with as many variations as you deem
necessary.

That's basically it! A little dexterity, and you've got this song
covered.  Questions?  Comments? Corrections? Please e—mail me.

Peace.
