Man on the Street Lyrics
'Bout an old man who never done wrong.
How he died no one can say,
They found him dead in the street one day.
At the man whose clothes 'n' shoes were torn.
There on the sidewalk he did lay,
They stopped 'n' stared 'n' went their way.
"Get up, old man, or I'm a-takin' you down."
He jabbed him once with his bully club
And the old man then rolled off the curb.

that is really sad.

I'll sing you a song, ain't very long, 'Bout an old man who never done wrong. How he died nobody can say, They found him dead in the street one day.
Well, the crowd, they gathered one fine morn, At the man whose clothes 'n' shoes were torn. There on the sidewalk he did lay, They stopped 'n' stared 'n' walked their way.
Well, the p'liceman come and he looked around, "Get up, old man, or I'm a-takin' you down." He jabbed him once with his billy club And the old man then rolled off the curb.
Well, he jabbed him again and loudly said, "Call the wagon; this man is dead." The wagon come, they loaded him in, I never saw the man again.
I've sung you my song, it ain't very long, 'Bout an old man who never done wrong. How he died no one can say, They found him dead in the street one day.

I think it's about people either ignoring the death around them as they go on with their lives, or the fact that we are not all that important in the scheme of things, because a man can sometimes die and no one notices.
