Darius Rucker will be joined by Luke Bryan, Dustin Lynch, Justin Moore, Randy Houser and others during his fourth annual Darius and Friends concert taking place Monday (June 3) at Nashville's Wildhorse Saloon. Sam Bush, John Cowan and Radney Foster will also perform during the sold-out event to benefit St. Jude Children's Research Hospital. "I always look forward to this event each year, and I'm so happy to have Luke, Sam, John, Randy, Dustin, Justin and, of course my hero, Radney, join me to help raise funds for St. Jude," Rucker said. "A few years ago, I visited the St. Jude campus in Memphis and instantly became a true believer in everyone there and the work they do to help treat kids and cure disease." On Tuesday, Rucker will host his Darius and Friends golf tournament in Nashville. Celebrity golfers expected to attend include Lynch, Moore, David Nail, Colt Ford, Lady Antebellum's Charles Kelley and Rascal Flatts members Jay DeMarcus and Jo Don Rooney, among others.
