a ceilidh without PA?

Greg - surely you haven't forgottent the rather excellent concert in the Prema at Dursley, with the rather excellent Boat Band.

OK Cajun, but enough of a dance floor and plenty of dancers even polkas and schottishes - and a song about a "man in Red". No PA there - so two thankyous at least. Make that three and gold stars.

And Bayou Seco don't need an amplifier for Village Halls. Mamou Mia!
It all depends on the size of the room and the courtesy of the audience. And courtesy is definitely on Angie and Ken's agenda, as I have been reminded by her once or twice!
