Bass lead in;  Bb A F D C

Intro:   F   Gm7/F bass  x 2

Gm7/C                         Bbmaj7
 I am a lineman for the county

Am7                         Gm7/C
And I drive the main road

Dm                   Am
Searchin'  in the sun

      G                        D
For another overload

                                     C+2
I hear you singing in the wires

                                    G/B bass
I can hear thru the whine

Gm/Bb                           D/A bass
And the Wichita Lineman

G add A/A bass      Bbmaj7  C+2   Bbmaj7    Gm7/C
Is still on the line

                                    Bbmaj7
I know I need a small   vacation 

Am7                              Gm7/C
But it don't look like rain

Dm                             Am
And if it snows that stretch down south

     G                                D
Will never stand the strain

                                               C2
And I need you more than want you

                                  G/B
And I want you for all time

Gm/Bb                         D/A
And the Wichita lineman

G+A/A bass         Bbmaj7   C+2   Bbmaj7   C+2
Is still on the line

Seen a few chord charts  for this, but I believe this to be about right with the 
correct bass progressions/ chord inversions. See what you think?
