Alright, so since I'm a girl and Randy Travis has a very low voice, I have put 
this version into a higher key for those of you who cannot sing as low as Randy Travis.

Capo 3
Key: G

G, Em, C, D

  G                       Em
A farmer and a teacher, a hooker and a preacher
C                        D
Riding on a midnight bus bound for Mexico
        G                            Em
One was headed for vacation, one for higher education
    C                D
And two of them were searchin' for a lost soul
          Em                        D
Well that driver never ever saw the stop sign
    C                                 D-----hang chord
And eighteen wheelers can't stop on a dime

There are


Chorus:
G                           Em                             C
Three wooden crosses on the right side of the highway
                              D                     G
Why there's not four of them, heaven only knows
                                Em
It's not what you take when you leave this world behind you
     C                D-hang chord
It's what you leave behind you when you go

G, Em, C, D

Verse:
          G                        Em
Well that farmer left a harvest, a home and eighty acres
  C                                 D  
A faith and love for growin' things in his young son's heart
         G                              Em
And that teacher left her wisdom in the mind's of lots of children
        C                 D
Did her best to give them all a better start
         Em                                     D
And that preacher whispered, "can't you see the promised land?"
              C                                   D-----hand chord
As he lay his bloodstained bible in that hooker's hand

There are

Chorus:
G                           Em                            C
Three wooden crosses on the right side of the highway
                              D                           G
Why there's not four of them, heaven only knows
                                Em                       
It's not what you take when you leave this world behind you
     C                D-hang chord
It's what you leave behind you when you go

G, Em, C, D

Bridge:
                Em             D                  C
Well that's the story that our preacher told last sunday
      G                                   D
As he held that bloodstained bible up for all of us to see
                    Em             D               C
He said, "bless the farmer and the teacher and the preacher"
              C                     D-----------------hang chord
Who gave this bible to my mama, who read it to me

There are


Chorus:
G                           Em                             C
Three wooden crosses on the right side of the highway
                              D                         G
Why there's not four of them, now I guess we know
                                Em
It's not what you take when you leave this world behind you
     C                D-hang chord
It's what you leave behind you when you go

G, Em, C, D and finish with G
