the very English "Good enough for folk"

This was coined by Alex Campbell when tuning (and failing dismally to do so). A very non-English, very Scottish self-aggrandiser.

Richard Bridge has still not read (or at any rate grasped) the original concept of "Does f*lk need professionals?" which refers to an attack on an agent, not performance standards though these must necessarily enter into the discussion.

Rephrase it, if you like, to "Do we need movers and shakers or will tthe music move and shake itself? I think it doesn't and won't. You may argue otherwise, if you can, and yes, without resorting to 'prolier than thou' or indeed dragging in other musics which are irrelevant to the topic.
