The Last  Letter.
Merle Haggard.
Album: Ramblin' Fever.

Intro: Bb Eb E F Dm Bb

Bb                              Bbmaj7         F7 C7 F F7
Why do you treat me as if I were only a friend?
         F6        F             C       Fm7 F           Bb
And what have I've done that has made you so distant and cold,
Bb                                        Eb    F7
Sometimes I wonder if you'll be contented again,
               F           Dm  F7          Bbmaj7  Gm Bbm
Will you be happy when you are withered and old?

Bb                                      Gm7 F
I cannot offer you diamonds or a mansion so fine,
  F7           F                           G/F  Bb
I cannot offer you clothes that your young body craves,
Bb                                           Fm Eb
But if you will say that you long to forever be mine,
F                                         Dm     F      Bb
Think of the heartaches the tears and the sorrow you'll save.

Bb                                            F
While I am writing this letter I think of the past,
F7              F        C   F            Dm Bb
And of the promises that you are breaking so free,
Bb                                     Bb/D        Eb
But to this old world I'll soon say my farewell at last,
F                                 F7   F6          Bb
I will be gone when you read this last letter from me.
