pmb - not sure, last time I looked in on it it was predominetly Irish music which is fine for those of us who can play it - I had in mind something on the slightly more 'gentle' side as far as pace so as to encourage those who have so far not ventured out to sessions.
As far as singers go I can't think of any valid reason why they wouldn't be most welcome! but first we have to have a few musicians otherwise it would be me and an occsional singer!
