Over the past six years, Darius Rucker has raised more than $400,000 for St. Jude Children's Research Hospital through his annual benefit concert, golf tournament and celebrity auction. Expect that number to rise by six figures after the numbers come in from Monday's sold-out show at Nashville's Wildhorse Saloon, along with today's golf match. The "Southern Style" singer was joined by buddies Little Big Town, Steve Wariner, Scotty McCreery, Brothers Osborne and A Thousand Horses for the event, which included chart-topping hits, throwback covers and plenty of singalongs.
