The song goes like this. Intro: Play the intro. Play three verses, then play B1 four times. Then play one more verse, then B1 four times. Finally play another verse followed by B1 three times, then finish. I hope thats right... There may be variations in the Bass notes or the extra notes Mark drops in all the time. The B1 bit is tricky - The idea in the second part of the bar is to get the bass notes going along in the background to establish the rythm, while the high strings give the note (guitartabs.cc)
