Thanks Jim.
it seems a reasonable assumption,that if singers/musicians go to workshops they will improve.
the club Bryan Creer is involved with runs workshops,many folk festivals run workshops[not sure if there are many singing workshops].
I think that this is where folk clubs can really play an important part in helping to raise standards.
folkclubs are also social clubs,where people often know one another, where hopefully people dont mind constructive criticism,it seems a good idea to me to employ a guest to do a gig and also help run a workshop,or for the residents to run a workshop before the club.
