TORONTO When the stage version of J.R.R. Tolkien's "Lord of the Rings" opens here in spring, the show is expected to feature about 18 songs, a cast of 55 and about 12 million investors. Literally. That's because, in an act of unprecedented governmental showmanship, Ontario's officials - on behalf of their 12 million citizens - have signed on as investors for the show, which is expected to be one of the most expensive ever. Taking on a role traditionally played by impresarios, idealists and other theatrical gamblers, the provincial government will contribute some 3 million Canadian dollars, or about $2.5 million, of the show's $23 million budget, betting that the production's global appeal will justify a unique, and risky, public-private partnership.
