Introduction:

These are the chord shapes -- listen to a recording for
timing and strumming information.

                        D     D    A    D
       H-O   H-O
E|------------------------------------|
B|-------------------10---7---5-------|
G|---------------7---7----7---6---7---|
D|----------7-9------7----7---7---7---|
A|-----7-9------------------------9---|
E|--10--------------------------------|

Repeat as necessary for intro.

Then

A  D  (x4)     Then repeat Introductory sequence...

Back to A  D, until this part (again, listen to a recording
for timing information and when it comes:

E|-----------------------|
B|--10--9--10--9--10--9--|
G|---7--7---7--7---7--7--|
D|---7--7---7--7---7--7--|
A|-----------------------|
E|-----------------------| then noodle on D...

E|------------------------|
B|--10--9--10--11--10--9--|
G|---7--7---7--12---7--7--|
D|---7--7---7--13---7--7--|
A|------------------------|
E|------------------------|


Repeat twice...

Then back to the main lick, then A > D, the last time ending with
a D chord on the second fret (basic D chord).

Then comes the distortion, and the progression changes to a
D C D C G > F one (See below)... listen to the recording for timing.
This is the solo Trey does on Lawn Boy.. every time I think he
noodles around with it a little.

    ~~~~~  ~~~~~   ~~
E|---------------------------5-4-3-----------------------|
B|------------------------(3)------3---3-5-3-5^(7)-------|
G|----------------------(2)----------4-------------------|
D|-------------------------------------------------------|
A|---5------3-------5------------------------------------|
E|-------------------------------------------------------|

              Palm muting...
E|-------------------------------------------------------|
B|--5^(7)-5-3-------------------------------5^(7)-5-3----|
G|-------------2-2-2-2-2-2-2-2-2-2-2---------------------|
D|-----------------------------------4-------------------|
A|-------------------------------------------------------|
E|-------------------------------------------------------|

E|----------------5^(7)----------------------------------|
B|-----------------------------------5^(7)-5-3-----------|
G|--2-2-2-2-2-2-2-------2-2-2-2-...2------------2--------|
D|-------------------------------------------------------|
A|-------------------------------------------------------|
E|-------------------------------------------------------|

E|--------------------------5^(7)----5^(7)-5-2-----------|
B|---------3-5-5-5-3---3-----------------------5-3--3----|
G|----2-4------------4----------------------------4------|
D|--4----------------------------------------------------|
A|-------------------------------------------------------|
E|-------------------------------------------------------|

E|---------------|
B|-15^(17)-15----|
G|------------14-|
D|---------------|
A|---------------|
E|---------------|


Then:
  Rake            Fast!!! ....................
E|---15---15--------15--14--13--12--7--6--5--4--3---0------|
B|--13-------13---15--14--13--12--7--6--5--4--3--2--0------|
G|-14-----------------------------------------------0------|
D|--------------------------------------------------2------|
A|--------------------------------------------------2------|
E|--------------------------------------------------0------|

..Into the JAM!!

Em > D

Here's a little lick that Trey did at Shoreline in 1995 at the start:
(Thanks to Mike Flouton)
E|--------------------------------------------------------|
B|-12h13-11h12------10------------------------------------|
G|-------------9h11----12-11-10-9-8-7-----7-9-------------|
D|------------------------------------8h9-----9p8p7-------|
A|--------------------------------------------------9p8p7-|
E|--------------------------------------------------------|

After the Climax of the jam, it cools down but maintains the same
Em > D progression.  Trey might noodle over it a little, then goes
into the words :

  Rai rai Rocko (?)

  Marco Esquandolas (?)

  Been you to have any spice/spike mon?  (?)

A heavy C chord makes for the transition to the next part:

D  C   D   C       G > F (loud!)

I like to play the G > F chords as such:

      G     F
E|--------------|
B|-----8-----6--|
G|-----7-----5--|
D|-----9-----7--|
A|----10-----8--|
E|--------------|

Though I'm sure most people will stick with the barre chord shapes.

For this part, I can't decide which one sounds better / works better - the
C chord or the Am or the Am7 chord.  They're all very closely related, Am
being the sixth of C.  Play it however you like, I suppose

           D                    /           Am7
 Run Run Run Run Run Run Run Run/Run Run Run Run Run Run Run Run

           D                    /           Am7
 Run Run Run Run Run Run Run Run/Run Run Run Run Run Run Run Run
