I think this is correct, but I'm not quite sure whether the chord
played while Corb Says: If you ain't been... is an Fm or not, but 
if another chord sounds better to you then please comment a correction!
Please rate, comment, and enjoy!

Capo 4th

C
I was mindin' my business and holdin' the fort
    F
And I still remember how you sallied forth
       C
And my mind, it was busy, warnin' my heart
           F                         Fm                C
But, hell, you ain't a cowboy if you ain't been bucked off 


The story's familiar, the oldest tale in the west
  F
I fell into love then the bird left the nest
       C
Well I guess that there's reasons we let our hard hearts go soft
    F                         Fm                C
And you ain't a cowboy if you ain't been bucked off
[ Tab from: http://www.guitaretab.com/c/corb-lund-band/338901.html ]
        F                                  C 
There's all kinds of horses will leave you grabbin' the breeze
F                            C
Busted up and broken up with scars you can't see
           Fm                             C
But if you ain't been bucked off and been throwed a few times
   Fm                               C
It don't count for nothin' when you make that last ride

         C
Well the years have passed quickly and ain't nothin's the same
     F
Only I don't feel different and you've hardly changed
       C
Well I guess what I'm sayin' is I'll give one last nod
       F                         Fm                C   
'Cause you ain't a cowboy if you ain't been bucked off
     F                          Fm                C
Nahh you ain't a cowboy, if you ain't been bucked off
