This is my transcription of the song. I'm fairly confident that any remaining errors are minor.

CAPETOWN
(Don Clarke) (tune: Dark woman of the glen)

The sun it shines like murder as it stares us in the face
dust beats in palls off the road-o,
the policemen they have dogs
and they're waiting by the bogs,
but we have no fear we've been this way before.

Our comrade lies in prison for the telling of the truth
the way he looks, the place that he was was born-o.
In his cell he lies in rags
near the house with all the plaques
where the minister is sipping on his tea.

CHORUS
We will walk together though some of us are lame
some of us are weary, sick and sore-o.
They may throw us into jail
but we'll die before we fail.
We will walk along together to Capetown.

Last time we walked together the army shed our blood
charged with horses, laid us down with gas-o,
but we'll let all people know
we'll not run before our foe,
we will walk as long as one of us can stand.

CHORUS

They say that his journey will take a thousand years
some of us will die along the road-o,
but to follow on your friends
to stand up like women and men
it is better for to living on your knees.

CHORUS
