Hi
I'm guessing that Sharper's Joe Jones is the singer who's included on this CD
https://www.mustrad.org.uk/articles/luck.htmI also have some recordings of him made 1965-1967 by Stephen Sedley, when Joe was camped at Biggin Hill and gave his name as Joe Saunders. I'm 99% sure it's the same singer.
Stephen Sedley says "Joe’s caravan, which he shared with his grown-up daughter Liza, was stationed on farmland on Biggin Hill with the agreement of a friendly farmer. Joe wouldn’t sing a note without a quart of cider, but once this was provided he was unstoppable".
There's a mention of him on my folk song website Kent Trad at
https://kenttrad.org/stephen-sedleyI haven't felt able to write up an article on Joe himself yet, as I've found it difficult to locate much information about him - possibly because he used several different surnames. Stephen Sedley mentioned that he sometimes went by the name of Ridley.
Now there's a Nelson Ridley who was recorded in the 1970s in Essex and features on this CD-ROM
https://www.mustrad.org.uk/download/254.htmYou can download it for 2 quid from
https://www.mustrad.org.uk/download/covers.htm - lots of tracks of Nelson singing on it.
I believe he was born 1913, died 1976. I had his parents as Alfred Smith and Louisa Jones, but that may be wrong.
I don't know if that's relevant or of any help.
If they are the people you're related to, I'd really like to hear back from you so I can do them justice on my website.
best wishes
