Every year, a team of ex-NHLers, including such greats as Bobby Hull, Tiger Williams and Frank Mahovlich, travels around Canada playing hockey and raising money for charity. Known as the "NHL Oldtimers" or "Legendary Heroes of Hockey," they get the kind of attention that Mario Lemieux and Paul Kariya get today. When the Oldtimers played in Edmonton last year, 15,000 fans attended. In Winnipeg, the 17,000-seat arena was sold out; and the 20,000-seat Calgary Saddledome is sold out every year for their games.
