After the bass intro, which follows the guitar part (or vice versa, I suppose!):
E|------------------|------------------|------------------|------------------|
B|------------------|------------------|------------------|------------------|
G|------------------|------------------|------------------|------------------|
D|------------------|------------------|---------------5--|-----9---9/109\8--|
A|-2-2-2-2-2---2-4--|---5-5---5---5-5--|-5-5-5-5-5---5-3--|-----7---7/8-7\6--|
E|-0-0-0-0-0---0-2--|---3-3---3---3-3--|-3-3-3-3-3---3----|---0--------------|

(This intro bit actually goes E G Ab C Db, rather than E F# G C, as is
shown here for the first three measures.)

E|------------------|------------------|
B|-------------3----|------------------|
G|-----0-----0---0--|-----0------------|
D|-------0----------|---4---2------5h7-| Play this four times, but on the 2nd
A|---2-----3--------|-5-----0---5h7----| and 4th times, substitute the
E|-0----------------|------------------| hammer-ons with a slide back down...

... now repeat, then into the chorus, heavily vibratoed:                A.H.
E|------------------|------------------|------------------|------------------|
B|------------------|------------------|------------------|------------------|
G|------------------|------------------|------------------|---999\7-777\6----|
D|---------7-5------|------5--------5--|---------7-5------|----------------5-|
A|-----3-5-----9-7--|---757----7-757---|-----3-5-----9-7--|---777\5-555\4----|
E|-3----------------|------------------|-3----------------|--------------3---|

Guitar 1 just does a slow gallop rhythm on an open B, while guitar two plays
this: (The gallop riff goes (6) open, 2nd fret, 3rd fret in rhythm, or something
like that)
E|------------------|------------------|------------------|------------------|
B|------------------|------------------|------------------|------------------|
G|------------------|------------------|------------------|------------------|
D|------------------|-----------9-11---|------------------|------------------|
A|-2----------------|-----------7-9----|------------------|------------(9)---|
E|-0----------------|------------------|------------------|------------(7)---|
                                                                slide down neck

(And I think that should prob be G5, not F#5 if I recall right, but I
haven't listened to the song in ages).

After the lead... after the first two repetitions, this is harmonised up
a fifth:
E|----------------------------------------|
B|----------------------------------------|
G|----------------------------------------|
D|------5------55h7p5-4--------5----------|
A|-7-757-7--5-7---------5-7-757-7---------|
E|----------------------------------------|

 Jon offers the alternative suggestion for the chorus:
E|----------------------|--------------------------|
B|----------------------|--------------------------|
G|----------------------|--------------------------|
D|--------5/7--5--------|-------5------------------|
A|--2--2--5-------7/9-7-|-7-5-7----7-5---5---5-7---|
E|--3-------------------|--------------7---7-------|
