Radney Foster celebrated his 50th birthday with a concert at the Exit/In on Monday night (July 20) in Nashville. Foster performed for more than two hours, bringing up several friends and admirers. Dierks Bentley joined him for "Until It's Gone" and "Sweet and Wild," while Darius Rucker sang on "Angel Flight" and "Raining on Sunday." Other guest performers included Jessi Alexander, George Ducas, Julien Foster (Radney's 18-year-old son), Vince Gill, Georgia Middleman, Lee Roy Parnell, Jon Randall and the Randy Rogers Band, as well as a 16-piece gospel choir. Foster and his Foster & Lloyd partner, Bill Lloyd, capped the night with their No. 1 hit, "Crazy Over You." Foster will release a new album, Revival, on Sept. 1.
