Country singer Keith Urban has compiled a star-studded line-up of famous friends, including Carrie Underwood and Reba Mcentire, for his upcoming Country Music Hall of Fame benefit. The You'll Think Of Me hitmaker and veteran musician Vince Gill are serving as co-musical directors for the fifth annual All 4 the Hall Benefit Concert, which takes place on 6 May (14) in America's country music capital, Nashville, Tennessee. Taking the Bridgestone Arena stage will be artists such as Brantley Gilbert, Deana Carter, Kacey Musgraves, Lee Ann Womack, Mary Chapin Carpenter and Ronnie Milsap. Urban shares his excitement for the event in a statement, which reads: "I think this is going to be an extremely unique and revealing night for everyone. Not only are we going to see extraordinary 'one of a kind' performances, but we're going to hear some stories that just may have us hearing these well known songs in a whole new way." Over the past four years, the concert has raised over $2 million (£1.2 million) for the Country Music Hall of Fame and Museum's preservation efforts, exhibitions and educational programmes.
