You have to play it properly, its tuned to Open C - (tune the 5th string
up a fret, the 3rd string down 2 frets, the 2nd string down 2 frets, and
the 1st string down 4 frets)

Intro:

E ----------------------|
C ---2------------------|
G ---0---12---------7---|
C ---0---11----7----6---|
G ---0----9----4----4---|
C ---0----9----4----4---|

E ----------------------|
C ---2--------------7---|
G ---0---12---------x---|
C ---0---11----7----6---|
G ---0----9----4----4---|
C ---0----9----4----4---|

The intro varies between these two parts, and then the 1st part is used
in the verse

Fill

E -------------------------|-------------------------|
C -------------------------|-------------------------|
G -------------------------|---------------------7---|
C -----4---4-4-6-6/7\6-4---|-----4---4-4-6-6/7\6-----|
G ---5---------------------|---5---------------------|
C -------------------------|-------------------------|

Where the horizontal lines are, towards the end of the fill, john
slowly adds

E ----------------|
C ------0-----0---|
G ----------------|

The next bit is like the intro, except for a few minor additions

C -----------------------------5-4-|
G ---0---12------------------------|
C ---0---11----7-------------------|
G ---0----9----4-------------------|
C ---0----9----4-------------------|

Play this twice, then
E ------------------12-10-------10---------|
C ---2--------------------12-11----12------|
G ---0---12---------------------------12---|
C ---0---11----7---------------------------|
G ---0----9----4---------------------------|

C ---0---11----7----6---|
G ---0----9----4----4---|
C ---0----9----4----4---|
