Country music artist Marty Stuart's Late Night Jam has recently added Gretchen Wilson and Old Crow Medicine Show to the June 4, 2008 performance.

The seventh annual Country Music event will officially be a part of the CMA Music Festival, and will again raise funds for MusiCares, the Recording Academy’s foundation. Monies raised from the Late Night Jam also will fund the CMA's "Keep the Music Playing" program, which places musical instruments in schools.

The Late Night Jam will begin June 4 at 10:00 p.m. at the Ryman Auditorium. Previously announced acts include Marty and his Fabulous Superlatives, Charlie Daniels Band, Mike Ferris, John Rich, The Steeldrivers, and Sunny Sweeney.
