C G

Intro chords in verses like so:

  G
I remember the Alamo
  C
I don't recall who won
         G
They had swords, they had horses
        C
I heard we had mighty guns
         G
Like the ones from Navarro
              C
Last night on channel 21
           Dm      D Dsus4
And it's a long way
           C   G
Back to El Paso

Then the chorus is:

G                     Dm
And if my heart was a car
             A                        Em
You would've stripped it a long time ago
G                     Dm
And if my heart was a car
             A                        Em
You would've stripped it a long time ago
G                     Dm
And if my heart was a car
             Em
You would've stripped it down and sold it off
To the greasy man in the salvage lot
As it is it's just a heart
Dm  D Dsus4
No, no
         C            G
It ain't worth nothing
