Here it is. I don't think they are playing on the 2 or 3 first strings because it will sound

too high-pitched.But if you want you can play this song like this:



 |-----------------------------------|

 |-----------------------------------|

 |-----------------------------------|

 |-----------------------------------|

 |-2-2-2-2-2-3-4-3--2-2-2-2-2-5-4-5--|

 |-0-0-0-0-0-1-2-1--0-0-0-0-0-3-2-3--|



This is the main riff:I love it!!
