The spacing of this tab does not accurately reflect the timing of the song, but listen 
and you should be able to figure out the timing easily.
This tab is partly structured from ajjose's tablature but I believe this is more correct 
and includes all of the
variations in the verses and small touches throughout.
Standard tuning.
