Yes, it can be like that, John C.
As an unaccompanied singer myself (but a concertina player too!), I have found that as the beer flows the boxes often become hyper and take it over at places like The Bricklayers.
But in the last couple of years there has been a singaround at The Boat on the Saturday night. Derek & Mary Droscher (Mudcat name: Merek&Dairy, I think!), who run the Banbury FC & FF, set it up. We will both be sheltering our campervans in The Boat car park again this year.
So, if it happens again this year, perhaps we will see you there?
