C 
When there's varmints need a'catchin' 

Am
And youngin's need a savin'

C                                    Em
On my rocket steed I race across the stars
         F            G           Am
For I've sworn by the burrs of my astro-spurs

   F                G         Am
To right the outlaw wrongs on mars
       F                 G         C    G7
Yes he rights the outlaw wrongs on mars

C
Oh the Hyper-cattle's hummin'

Am
And the Margins' savage drummin'

       C                          Em
Are as beautiful as comet bugs in jars

    F    G     Am   (G Am)
Oh, I'm   from Earth

      F                G         Am
But I right the outlaw wrongs on mars

       F                 G         C Cmaj7 C7
Yes he rights the outlaw wrongs on mars

       F                   G        C
On the plains (a') the red planet I uphold the law

      F            G             C
And I do it with a pair of robot fists POW!

F      G           C G    Am
Evil extermination I have faced
       Bb                            G
For my robot rogues they hardly ever miss

      C
And I reckon I'll be ridin'

       Am
In the name of truth & justice

       C                                 Em
For as long as I can count the shooting stars

         F            G           Am,
For I've sworn by the burrs of my astro-spurs

   F                G         Am
To right the outlaw wrongs on mars

       F                 G         G# - Bb - C
Yes he rights the outlaw wrongs on mars

And I''m from Earth
