Musicians' Strike Delays Rockette Show Opening Christmas in New York would hardly be Christmas without the Rockettes, whose Radio City Christmas Spectacular was set to open Thursday night, as it has for 70 years. But the musicians went on strike, apparently not convinced that the show's Christmas spirit extends to their salaries. Some ticketholders burst into tears. There are rumors the Rockettes may walk -- or kick -- out in solidarity. So far that hasn't happened and the show will go on, with recorded music.
