[Verse 1]

C                     C6/9       C
    You were born in a southern fall,
C                                 C6/9       C
    It might've been Sunday but I can't recall
C                       C6/9        C
    All the birthdays I must have missed
Am                          C[Fill 1]  Fm
    Your first steps and your first kiss
C                            C6/9      C
    I don't even know if you know my name
                    Am             G[bass]         C[Fill 1}   Fm
    But you should hear the truth before it's too late


[Chorus 1]

                    C                     G
    So I hope this finds you, on some highway
F                          C      F                  C
    Cause I'm a long time rambler, I call the road my home
F                    C                 G
    Forgive my indiscretion, it's the only way I know
F                            C                Am     G     C     Fm
    A million miles from Kentucky, but I will always be around
                 C                  C6/9          C
    So turn the radio up when your heart breaks down


[Verse 2]

          C                        C6/9         C
    I've played for tips and I've played for less
                C                          C6/9         C
    I played a pretty southern girl right out of her dress
        C                 C6/9          C
    She danced until the lights came on
                   Am                           G       C[Fill 1]   Fm
    But there's a reason she's here instead of being at home
                   C                       C6/9         C
    She said "the songs you sing make the whole room cry"
             Am             G           C[Fill 1]   Fm 
    And that night I told a young man's lie


[Chorus 2]

                         C                         G
    When I said I would call her, and I said I'll write
F                          C      F                  C
    Cause I'm a long time rambler, I call the road my home
F                    C                 G
    Forgive my indiscretion, it's the only way I know
F                            C                Am     G     C     Fm
    A million miles from Kentucky, but I will always be around
                 C                  C6/9          C
    So turn the radio up when your heart breaks down
              C                  C6/9           C       C/B
    Turn the radio up when your heart breaks down


[Bridge]

Am                    Am/G              Dsus
    I'm sorry for the tears I made you cry

    I'm sorry for the promises that turned to lies
Am                  Am/G               Dsus
    If I could turn back the hands of time

    I'd take it back and try, try, try
       Am                         Dsus               C    C6/9  C
    To make you understand, that this is who I am


[Verse 3]

C                         C6/9     C
    I met the devil in an old motel
C                                  C6/9       C
    It seems I ain't got much of a soul to sell
C                          C6/9       C
    My glass is empty, my hands are blue
         Am               G         C[Fill 1]  Fm
    And the doctor gave me 'bout a month or two
            C                         C6/9        C
    Well I thought I would make it to you this year
           Am               G       C[Fill 1]  Fm
    So forgive me one last time my dear


[Chorus 3]

                  C                          G
    And tell your mother, I won't be coming home
F                          C      F                  C
    Cause I'm a long time rambler, I call the road my home
F                    C                 G
    Forgive my indiscretion, it's the only way I know
F                            C                Am     G     C     Fm
    A million miles from Kentucky, but I will always be around
                 C                  C6/9          C
    So turn the radio up when your heart breaks down
              C                  C6/9           C
    Turn the radio up when your heart breaks down
