E5
Blue, blue driver
Rolling along
A5
Searching the endless highway
      A5                E5
for a shoulder to cry on
  A5                E5
A shoulder to cry on

E5
Blue endless highway
Where do you come from
A5
Blue endless highway
A5            E5
Where do you go
A5            E5
Where do you go

E5
It don't make no difference
Which way you go

I'm so doggone lonesome
A5        E5
Anyway I go

Anyway I go

Chorus:
A5               B5
Foot upon the throttle
A5                      B5
Watching the old small road
A5                         E5
Looking out the rear-view mirror
        A5           E5
for the highway patrol
    A5           E5
The highway patrol

E5
Make my coffee stop
Everything was wrong
A5
Little witches that I loved
A5                 E5
She had come and gone
A5                 E5
She had come and gone

     E5
That big old lonesome moon
and the stars above
A5
Carry me on old drug
A5             E5
To the one I love
A5             E5
To the one I love

Chorus

E5
Looking down the highway
As far as I can see
A5
There ain't nobody coming
A5                 E5
My old truck and me
A5                 E5
My old truck and me

Chorus

    E5
I'm looking down the highway
As far as I can see
A5
There ain't nobody coming
A5                 E5
My old truck and me
A5                 E5
My old truck and me

End by playing the intro riff a couple of times
