e -------------------------|

G -/13--13/17-17-17/-18-\--| use the slide for this as well
D -------------------------|

E -------------------------|

e -------------------------|

G -/13--13/17-17-17/-18-\--| use this if you want to be different =D
D -------------------------|
A -/11--11/15-15-15/-16-\--|
E -------------------------|

Thats basically it the whole way through. Between the first and second parts he just

was any point tabbing that bit.

Well, enjoy.
