Calais Celtic Concerts is extremely pleased to present the Internationally acclaimed, award-winning, musical sister-duo of Cassie and Maggie MacDonald, who are no strangers to Celtic Christmas, Holiday Magic! The sisters are part of a multi-generational musical dynasty, in which Christmas was always a time to gather near and sing boisterously, as in the days of old. The doors were always open to company when the New Year was just around the corner.
