I didn't say that a session run by the people from the volunteer with guest artists would be a non-starter but I stand by my statement that it would not be a transplanted volunteer session. It might attract different people but it would be, by the nature of the venue, so different that it is unlikely to appeal to the original crowd that enjoyed the volunteer session. Those displaced from the volunteer would probably still be looking for an alternative venue (in a pub), so we then have two groups looking for a new venue not just one!
