The Charlene Question: BBC One Wales, 23/09/21

Remember Charlene's "I've Never Been to Me" hit from (yikes!) almost 40 years ago?
Yesterday I was listening to Randy Crawford's version from 1976 (yep, she released it first - there's a long article about it all on Wikipedia if you can be bothered).
Anyway, as the Rota Gods™ decided last night was my final closedown for a few weeks I thought I'd better ask the question we never did get an answer to at the time.
I have a feeling the answer has something to do with Arthur Negus.
