I don't think anyone here would argue that everything at the Lewes Arms is pretty near perfection, and that precocious toddlers are tottering in on a weekly basis to show of their skills on the McCann duet while gifted amateurs of all ages join in with gusto.
But that's completely beside the point.
The point being made is the the club circuit in general and overall is - in the opinions of some (myself included) - a poor advert for the world of traditional music, and is unlikely to attract and retain the young musicians and singers it once did.
Secondly, there seems to be a lack of self-assessment and plain pride in the material among many performers which, to the non-folk world, comes across as bumbling amateurishness rather than the work of talented amateurs.
The third point - the ramifications of folk's inclusivity and 'come all ye' nature - are perhaps too pointed to debate here without sparking the sort of personal attacks that do no-one any favours.
