The story of the marriage of England's King Arthur to Guinevere is played out amid the pagentry of Camelot. An all-star cast in this frothy, musical with Vanessa Redgrave putting on a stormtrooping performance as the monarch's lost love, Guinevere. At three hours of full-on, enthusiastically stagey tonsil-tickling, you need to be into musicals in a big, big way to enjoy this.
