Ver. 2 was correct except for a couple of parts where it is difficult to tell 
whether it is a chord or its relative minor (i.e. G vs Em, C vs Am). You'll notice 
the difference if you listen to the first verse closely.

Capo on 1st fret

Intro: F C Em, F C G

F
Please take a long hard look
                      C          Em
Through your text book cause I'm history
F
When I strap my helmet on I'll be long gone
C                         G
Cause I've been dying to leave
     F
Yeah, I'll ride the range
                             C     Em
And hide all my loose change in my bedroom
F
Cause riding a dirt bike down a turn pike
C                G     
Always takes its toll on me

F Am G Dm

                   F
I've had just about enough
                          Am
Of cloaked diamonds in the rough
                               G
Because my back-bone is paper thin
                                    Dm
Get me out of this cavern or I'll cave in

(I'll cave in, I'll cave in...)
Am              G                       Dm
If the bombs go off the sun will still be shining

(The sun will still be shining)
F                      Am
Because I've heard it said that
                 G                  F
Every mushroom cloud has a silver lining
                            G
(Though I'm always under mining to deep to know)


F
Swallow a drop of gravel and blacktop
C                          Em
Cause the road tastes like Wintergreen
F
The wind and rain smell of oil and octane
C                  G
Mixed with stale gasoline
    F
I'll soak up the sound

Try to sleep on the wet ground
C                    Em
I'll get ten minutes give or take
    F
Cause I just don't foresee myself getting drowsy
C                  G
When cold integrity keeps me wide awake

(C-Am-(C)-G-(C/E)-F)
(Awake, awake, awake, awake...)
Get me out of this cavern or I'll cave in
(Cave in, cave in, cave in, cave in...)
Get me out of this cavern or I'll cave in
(Cave in, cave in, cave in, cave in...)

F C F-C-G (2X)

C                   G
I'll keep my helmet on
                Am           F
Just in case my head caves in
(In case my head caves in)
            Am         
Cause if my thoughts collapse
   G
Or my brain work snaps
      F          G
It'll make a mess like you wouldn't believe
C             G     
Tie my handle bars to the stars
     Am             F
So I stay on track (so I stay on track)
          Am                     G
And if my intentions trail I'll wrench them away
          F            G
Then I'll take my leave and I won't even look back

(C-Dm-F-G)
I won't even look back

Outro: Same as intro
