               C#m
Hustle up the spiral stairs
                 Bm
See if anyone's left up there
              G
Teams on the scene from several stations
             F#m
Everybody, adjust your expectations
                C#m
Stray clumps of hair and blood and brain
             Bm
Fragments of bone in the drain
                           G
Rookies trying to keep the airway clear
                  Bm           C#
But the damage is too severe


               D7M/A               A7M/E
Bring in the cadaver sniffing dog  
               D7M/A               A7M/E
Bring in the cadaver sniffing dog  
               D7M/A               A7M/E
Bring in the cadaver sniffing dog

[Solo]


F#m                   C#m
Army crawlers down ash wet floor
Bm
Ready for war
                  G
Veterans on their hands and knees
                   F#m
Nobody's ready for days like these
                               C#m
Wait till you come up on the smoking wreck
        Bm
And even then you check
      G
Radio home all clean
                     Bm                             C#
If there were any survivors they've fled the scene


               D7M/A               A7M/E
Bring in the cadaver sniffing dog 
               D7M/A               A7M/E
Bring in the cadaver sniffing dog  
               D7M/A               A7M/E
Bring in the cadaver sniffing dog

Bring in the cadaver sniffing dog

[Insert sickass guitar solo over the intro chords, and the rest of the song is identical to the first half]

Army crawlers down ash wet floor
Ready for war

Veterans on their hands and knees
Nobody's ready for days like these

Wait 'til you come up on the smoking wreck
And even then you check

Radio home all clean
If there were any survivors they've fled the scene


Bring in the cadaver

Bring in the cadaver
Sniffing dog
