I haven't found a correct version of this song yet.  First, the tuning is not standard, 
is open G.  Im not going to tab the whole song but this should give an idea.  Listening 
the song will give an easy view on the rhythm and   changes.

NOTE:  The G and B chords are palm muted for two strums and then accented on the last,
