The song is The Lochmaben Harper. You can find a set of words here in the DT: The Lochmaben Harper, but the source is not Nic'a recording. The story is also given in the thread: Story Add: The Lochmaben Harper, where you will see in Malcolm Douglas' post that "Nic Jones' set was on From the Devil to a Stranger (Transatlantic LTRA 507, 1978), and is unfortunately one of those being withheld by "Celtic Music" of Harrogate"

You can find a transcription of Nic's version at Selected English Folk Singers - Nic Jones. Go down to the album given as From The Devil A Stranger (sic) and click on the link for The Blind Harper for the words. I haven't checked the transcription (they were unsure of Lochmaben at least); if I have time later I'll check it against the record.
