[Intro]
G G G G

[Verse 1]
G                                        G
Well, you wonder why I always dress in black,
G                                       A
Why you never see bright colors on my back,
C                  G               C              G
And why does my appearance seem to have a somber tone.
A7                                                D7 
Well, there's a reason for the things that I have on.

[Verse 2]
G                                              G
I wear the black for the poor and the beaten down,
G                                       A
Livin' in the hopeless, hungry side of town,
C                   G                   C              G
I wear it for the prisoner who has long paid for his crime,
A7                                          D7 
But is there because he's a victim of the times.

[Verse 3]
G                                      G
I wear the black for those who never read,
G                                     A
Or listened to the words that Jesus said,
C                      G              C           G
About the road to happiness through love and charity,
A7                                               D7 
Why, you'd think He's talking straight to you and me.

[Verse 4]
G                                         G 
Well, we're doin' mighty fine, I do suppose,
G                                          A
In our streak of lightnin' cars and fancy clothes,
C                     G           C                   G
But just so we're reminded of the ones who are held back,
A7                                   D7 
Up front there ought 'a be a Man In Black.

[Verse 5]
G                                  G 
I wear it for the sick and lonely old,
G                                               A
For the reckless ones whose bad trip left them cold,
C                      G               C                   G
I wear the black in mournin' for the lives that could have been,
A7                                      D7 
Each week we lose a hundred fine young men.

[Chorus]
G                                           G 
And, I wear it for the thousands who have died,
G                                     A
Believen' that the Lord is on their side,
C                G               C                G 
I wear it for another hundred thousand who have died,
A7                                   D7
Believen' that we all were on their side.

[Verse 6]
G                                                G
Well, there's things that never will be right I know,
G                                       A
And things need changin' everywhere you go,
C                    G               C                   G
But 'til we start to make a move to make a few things right,
A7                                  D7
You'll never see me wear a suit of white.

[Verse 7]
G                                      G
Oh, I'd love to wear a rainbow every day,
G                                     A
And tell the world that everything's ok,
C                      G             C               G
But I'll try to carry off a little darkness on my back,
                A         D              G 
Till things are brighter, I'm the Man In Black
