I'm a member of the Folk club at the Golf hotel, but I wouldn't consider that a session where you pay to hear some play/sing.
A session for me is a pub or a place where anyone can play/sing for nothing.
The Irvine folk club is a business, unlike a session which isn't.
but that just my view, there might be people who think that going to a folk club and you pay, a session.

Thanks anyway.
