Thank you all for your comments and advice.
I will pass on the info (thanks Shambles) to The Cheesewring and hope to be able to re-establish this session as soon as possible. In the end it is up to the landlord to do what he can to achieve his desires. It is his place after all.
I will attend The Caradon session next Wednesday (if I've not got the date wrong again) and keep my fingers crossed that the rot has not set in.
Thanks again, Bo
