and this one which surprisingly is by Kate Wolf
as far as i know it is previously un-recorded:

LINKS IN THE CHAIN, by Kate Wolf,
    1979,    Another Sundown Music

Willing to go ahead
When other people were afraid
Remembered by the questions that they raised
Some dead, Some in prison,
For the things that they believed,
They were links in the chain.

    Just another link in the chain
    Just another link in the chain
    It's the truth growing stronger
    And the voices speaking louder
    That makes us links in the chain.

Who took the children from the mines
The young women from the mills
When the bosses turned to look the other way
It was the rebel voices raised against
The wind, raised high against the wind
That fought for the rights we have today.
   
(Tom Paxton added this verse:)
Joe Hill and Mother Jones
Put their lives right on the line
A line that stretches back in history
Now we ask ourselves the question
"Are those the days to be forgotten?"
Or are there some of us who'll dare to be?

It's the question and the answers
The knowing and the why
The standing up to wrong things that we see
And it takes more than one
Before the battle's won
Someone who is not afraid to be.
