4x total, second two power-chords play on top

Verse 1: (power-chords)
C#
Two tickets on a Chevrolet train
           A                        F#
I've got a suicide packed with your name
C# 
You can doubt any move that is made
         A                   F#
'Cause I put in the words to pay
C#
In a flash, he'll be quick to react
       A                   F#m
I'm a useful spade for the grave
C#
Black calls to the shadowy town
         A                        F#
I said, “What were the chances of saying”

Chorus:
         A          F#
You must remove the skin
         A       F#
And burn off the fuel

Intro x2

Verse 2:
Knocking teeth to improve how you look
And you're using your tongue for a flat
You look tired in your funeral suit
His caskets were all to be had

Real estate, cemetery move over
I'm useful as bones in the tomb
Gas drinks for the shadowy town
Another record is due

Chorus x2
