pretty sure its all accurate, lyrics taken from some random site but seem accurate too.
standard tuning
i recommend the following chord positions, they are the easiest/best sounding in my 
opinion. Your results my vary. played with a reggae feel on the off beat, mostly the e,b,g 
strings but i put the full chords if that tickles your fancy.
