One thing that 'Folk Clubs' in general have in their favour is the one thing that can count very heavily against them , and that is the overall politeness of 'Folkies' . If some one gets up on their back legs , wether as a floor singer on a Guest night , or at a Singers night and is Diabolically BAD , No one will say anything , just not be QUITE so enthusuastic in the level of applause .
I accept that it is NOT easy to tell someone that they need to do what ever is required to improve , but in my experience , it VERY seldom happens ! And when the same person , after TEN years (No Names ,No packdrill) is still TOTALLY surprised that at a singearound THEY are next after the person alongside then has sung .
No WONDER new attendees at some clubs are not so keen to come back !
