You can get away with a D where there is an G/F#, especially in the chorus. 
  
  
G    G/F#        Em                C         G        G/F#     C 
Everyday someone asks me what?s my story and what do I like to do   
G   G/F#              Em                C     G             G/F#           C 
And everyday, for the most part, I only go so far; I almost never tell the truth   
           G          G/F#            Em           C               G       G/F#      C 
?Cause the truth is behind me there?s not much, to give up, I like simple, not complicated   
 

               G                      G/F#                   Em                 C 
(?Cause) I?m a small town kid, driven by rock music And some honky-tonk, in the mix   
       G                  G/F#                         Em             C 
I like whiskey in coke, a double to the top, a shot of cuervo now and then   
        G                         G/F#              Em                        C               G 
I never ask for a lot, I?ll never need much, just a good-looking lady who can drive my truck   
G        G/F#      C              D          G    G/F#  Em  C  G  G/F#  C  G 
I?m not afraid to admit, I?m that small town kid    
  
City lights, yellow cabs, Yankee hats, Suits and ties everywhere   

These City folks, they look at me in my shirt and jeans, they make me think I don?t fit in here   

Well the things they say might be right, they might be so but one thing I know: I can?t change who 

I am   
  
Chorus   
  
Bridge: 
D                    C   
Mama don?t you worry 
D                    C 
They won't change me   
D                  C 
A hundred thousand miles  
     D 
Mean nothing to me
