Scores of stars are gathering for the 'Hope for Haiti Now' telethon to benefit earthquake victims. But of course it's not the first time that celebs have donated their time and money in the time of tragedy, domestic or international. Televised concerts and even merchandise have been used to raise relief money for decades. Such efforts have seen huge success rates, with millions of dollars being brought in from high profile fundraisers. And with stars like George Clooney, Bono, Bruce Springsteen and Faith Hill taking part, the world sees a human side of Hollywood while helping out their fellow man.
