Top country music group Lonestar will perform a USO show for troops stationed at Keesler Air Force Base in Biloxi, Miss., Nov. 4. This special performance is open only to military personnel and their families. For the sixth consecutive year, the band is nominated for the Country Music Association's Vocal Group of the Year. This year's award will be handed out during the awards ceremony Nov. 15 on CBS. Home of the 81st Training Wing, Keesler Air Force Base is a major player in Hurricane Katrina relief efforts. Lonestar volunteered to perform the USO show after learning the base's annual air show was cancelled due to the devastating storm.
