Hi MoorleyMan, sorry, no local knowledge.
But I put a few links on a thread last year
I think the westcumbriafolkmusic you've already found might have been the best of them though.
I notice Sticklebarn in the Langdale Valley has occasional gigs
The thread here describes first Wednesdays in cockermouth as 'folk' so I wonder if that's what remains of the weekly club :(
