The following Irish Singers Clubs that i have been to have a restrictive singing policy, no accompaniment allowed... Cork singers club, Skibbereen singers club.
that is a fact, the only other singers club that I know of the Góilín Traditional Singer's Club, at this moment in time appears to have a more relaxed policy,I understood that it used to have a more rigid policy.
I have never been to that club so of course I WAS TALKING FROM MY OWN EXPERIENCE.
