I envision a folk club where people can go and hear folk songs reasonably well performed

People can still go to folk clubs to hear 'folk songs reasonably well performed'. They can also go to concert halls, village halls, community centres, festivals, pubs, house parties, and any number of venues where they can hear the same. Some folk clubs did, rightly or wrongly, generate a poor image. It is the type of folk club that perpetuated that image that has, quite rightly, had its day.
