I'm not claiming this to be accurate - in fact, I've only been playing guitar 
for a few months. I just thought that the intro should be rather "simple" - and 
this sounds good to me. Let me know what you all think. This is based off the 
Chords to match up with the song - see axehappy's chords. I do use an Em7 
instead of an Em though - Em seems "too deep" and I couldn't get it to work 
with the intro.
