Interesting refrence to choirs earlier. In Penkhull, where I live, there is no folk club. But there is a pub session now and then, of a "good standard" I would say(following the Jim Carroll line in a recent post). And once a weeek in the church hall there is is a sort of community choir, or open-access group of singers, who practise harmony singing of old carols etc. Folk clubs are definitely not the only places to nurture traditional performance.
