(The bits in brackets are played on piano i think, but they sound good on guitar too)

Then this is played, let's call it Riff 1:
E|----------------------------------|
B|------3-----3---3-----3-----3---3-|
G|----2-----2---2-----0-----0---0---|
D|--0-----0---------0-----0---------|
A|----------------------------------|
E|----------------------------------|

This is repeated I don;t know how many times and then it goes back to the intro riff 
the verse. Then it goes back to riff 1 in the chorus, then the intro riff in the second 
Then riff 1 in the chorus and there's this bit after the second chorus, we'll call it riff 2:

(i really do feel so much better...)
