On the LP it is marked as "Trad., arr. Woods". The lyrics sound very contemporary to me, perhaps the "arr." is a bit too modest.

Anne Briggs at that time was travelling around with Sweeney's Men so she would have had access to all their material.

I now post my own transcription of the lyrics. It is one of my earlier attempts when I was worse at that than I am now, but I don't have the time to listen again before next week. So be careful, all below will still be full of errors. The most unclear bits are in parentheses.

STANDING ON THE SHORE

Through the mist my ship has sailed
leaving me behind
all the things left unsaid
that were in my mind.

When I stood on its deck
strangely things I saw
strangely they have vanished now
standing on the shore.

Memories of the seas I sailed
lands I gazed upon
when I turned to (draw the chart)
all (a land) were gone.

(Sundry) hills lying round
nothing standing clear
softly light is falling through
(brought) time was never here.

Headland fading out of sight
(rise ends) disappear
hazy shores and (silency)
nothing I do hear.

Hail and water, grass and sand
merging into one
in the silence of all this
I am still alone.

The logbook (closed too) the (ship has gone)
as it has done before
where it sails no tongue can tell
no one was aboard.
