It's that time of the year when four strangers from the east, the midlands and the north, come again to a town near you to bear witness to the Christmas miracle. Or something like that. St Agnes Fountain are Chris While, Julie Matthews, Chris Leslie and David Hughes and together they make some of the most beautiful - and entertaining - festive music we've ever heard. They're not coming very near Brighton on this tour - boo - but if you can catch them, we'd recommend it. A very special evening.
