E-|-----------------------------|
B-|---------------6--8--6vvv----|
G-|--5h7--7x--7x----------------| Then go right back into the
D-|-----------------------------| intro, after a few more times,
A-|-----------------------------| play:
D-|-----------------------------|

E-|---------------7b8rb7----(5)---|
B-|-----------------------8-(6)---|
G-|--5h7--7x--7x-------------7----|
D-|-------------------------------|
A-|-------------------------------|
D-|-------------------------------|

As a little aside here, most of the song is centered around two
chords, Dm and G. These are the chords you sometimes here being
played over these intro parts. If you ever get lost, revert to
either using them or playing along with the bass. My suggestions
for these are:
Dm G Bass Part
E-|--5--|------|--------------------------------------|
B-|--6--|--12--|--------------------------------------|
G-|--7--|--12--|--------------------------------------|
D-|--7--|--12--|---------------------5--0-------------|
A-|--5--|--10--|----5--0------------------------------|
D-|-----|------|----------0--0-0-0---------5--5-5-5---|

One of those should get you back on track.

Figures 1 and 2 shown below appear again and again throughout
the song, listen for where they fit in. And most of the leads (and
my attempt at the solo) is based on a Dm pentatonic scale. If you
need ideas for the leads, look at the solo.

Solo (I'll try to break it into phrases, if I indent a line, it means
that the new line is still a continuation of the last phrase. )
