Craig Morgan, Steve Holy and Neal McCoy will be Blake Shelton's special guests at his second annual Raindance charity event taking place April 22-24 in his hometown of Ada, Okla. In addition to an April 24 concert featuring the four singers, the event will include an archery tournament and a team roping competition. Last year's event raised more than $133,000 for the victims of Oklahoma's drought and subsequent wildfires that destroyed family farms, livestock and equipment in 2005 and 2006. Raindance has partnered with the Oklahoma Lumbermen's Association and their relief program, Project Rebuild, to distribute aid throughout the 28 counties of Oklahoma.
