We can't make the 28th, but it is good to hear of a new venue with accomodating owners. 7 champs had some ace musos I expect they still have. I'm not sure how wise it is to stipulate the type of session until it occurs. Most musicians can sing - but is not always the case the other way round. A night of unaccompanied singing can be a bit dire - a mixed session adds variety.
I was a bit disappointed not to hear you each sing the other tuesday each time the turn came, but it was a good night.
