I know I need a small   vacation

And if it snows that stretch down south

     G                                D
Will never stand the strain

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

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?
