Bass comes in at 0:14, after 8 measures
As far as I can hear, theres only one riff which repeats itself
throughout the song:

Key:
q = quarter note (crotchet)
e = eighth note (quaver)

  e q      e q      e q      e q      e
G  |--------|--------|--------|--------|
D  |3------3|--------|0------0|0-------|
A 3|--------|1------1|--------|-------3|
E  |--------|--------|--------|--------|

that's it!
