Weekly, conventional folk clubs around me - all less than an hour's drive (Sussex):

Amberley
Arundel
Chichester
Eastbourne
Horsham
Lewes (two)
Seaford
Tonbridge

And there may be others. Then there are monthly ones in places like Brighton.

But look at this: A local chap started a monthly folk club about3 months ago second Monday of the month - in an old pub (the Royal Oak) in a remote rural village in West Sussex (Wineham). Packed out from the start! Hardly any singers at first but lots of local people and nearby outsiders who wanted live music. More chairs are now needed... people not being able to get in... And, yes, it's got lots of traditional music in it (until buggers like me get in there and corrupt it, of course).
