There's one business like show business -- goldmining! Both have personality greats, those who strike it rich, who take the heartbreaks, hit top-of-the-bill, go under. Both are steeped in legendary romance, gaiety and hardship, deep disappointment, shilling success. Perhaps that is why Dawson City in Canada's Yukon -- scene of the great goldrush -- has its fabulous Palace Grand Theatre. Sixty-three years after it mushroomed amidst the rip-roaring hodge-podge of saloons, dental parlors, eating rooms and flop houses that held the Klondike spotlight in 1899, the old Palace Grand has made a comeback to link again the bright world of the footlights and the magic poke of gold in a miner's hand. From New York's Broadway -- famed for shows and music long before the first cry of gold echoed down from the Yukon -- has come world-famous Beatrice Lillie to open Dawson's Palace Grand and the premiere of Foxy -- a musical with celebrated comedian Bert Lahr and other top U. S. artists who will later take their hit comedy to New York.
