Hi Shambles
You better ask Pete & John for chapter and verse but, as I understand it, the reason for the change is that the main pub [was it the Ring of Bells?] in Cheriton Fitzpaine changed landlords and the new guy wasn't keen and then he decided to use the barn for something else.
Since then they have been looking for another suitable village and have been trying to deal with issues of entertainment licences, insurance and the Performing Rights mafia, etc...
