Rod is selling recordings of authentic traditional singers, not of folk revival performers. This is a minority interest even among those who like folk music. These are not singers who would very often be heard in folk clubs, if at all. What he does, which is admirable, has nothing to do with folk clubs.

"You are not honouring you promise to your audiences by calling yourself what you do 'folk' - you are in fact talking about song club" If that is the case then most folk clubs have been misdescribing themselves from the 60s onwards.

The decline of clubs probably has a number of causes, but I don't think the balance between traditionally sourced and other material has changed much, so I doubt this is the reason. What puts me off many clubs is not any lack of traditional music but the decline in standards, which has been discussed at length elsewhere. This is ironic, because at the other end of the scale standards of performance appear to be higher then ever, and young performers have access to better instruments and better tuition than ever before.
