I don't think the other versions posted are right. From the watching them play it live,
are playing barre chords down around the 5th fret till the chorus. Here's my version.
probably not 100% correct to how thy play it but it goes along with the album 
is a damn good song!

F                     C
Oh there's something 'bout a man in black,
D                  Bb5
Makes me want to buy a Cadillac,
F
Throw the top back,
    C           D      Bb5
And roll down to Jackson town,
F                      C
I wanna be there on the stage with you,
D                    Bb5
You and I could be the next rage too,
F
Hear the crowd roar,
         C
Make 'em want more,
         D        Bb5
Kick the footlights out,

Chorus:

F                C
I wanna love like Johnny and June,
D         Bb5
Rings of fire burnin' with you,
        F
I wanna walk the line,
C
Walk the line,
          D     Bb5
'Till the end of time,
F
I wanna love,
C
Love ya that much,
D
Cash it all in,
Bb5
Give it all up,
F                C        D    Bb5

Like Johnny and June


F                   C
I wanna hold you baby right or wrong,
D                    Bb5
Build a world around a country song,
F
Pray a sweet prayer,
C
Follow you there,
D         Bb5
Down in history

F               C
I wanna love like Johnny and June,
D            Bb5
Rings of fire burnin' with you,
        F
I wanna walk the line,
C
Walk the line,

'Till the end of time,
F
I wanna love,

Bridge:

A5      D     Bb5
More than life itself,
   C
No-one else,
     A5     D
This endless promise,
     Bb5
They don't make love like that anymore,

Is that too much to be askin' for,

I wanna love like Johnny and June,
D           Bb5
Rings of fire burnin' with you,

I wanna walk the line,
C
Walk the line,
          D     Bb5
'Till the end of time,
F
I wanna love,
C
Love ya that much,
D
Cash it all in,
Bb5
Give it all up,
F        C             D       Bb5
When you're gone, I wanna go too,
