this is how Tom paxton and Anne Hills sing it:
with an added verse...and other words substituted
for the Karen Silkwood line...

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
ther 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 form the rights we have today

tom paxton's 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 days to gbe forgotten?"
or arte ther some of us who'll dare to be?

it's the question and the answers
the knowing and the shy
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
