If you can't find it P.M. Dave the Gnome and he will give you my Email so I will send it to you.
Getting back to Lloyd's rewrites, he has been censured for his Australian collection and his industrial songs. I am not the least surprised that he altered Chanties. I think you have put it rather well Lighter, and the false glow of an imagined historical past is very seductive. Certainly a fantasy, but then again so are the songs themselves. Maybe they leave you a little more able to wrestle your way through the reality of the day even if they were rewritten by a seven-dials pot poet or Mr Lloyd.
