Here's proof when you do something good, something good comes back to you.   Kenny Chesney is turning his concert next Wednesday in Tuscaloosa into a benefit for victims of tornados in the Alabama town.   He's donating all the proceeds from the show to GiveTuscaloosa.com to go toward local charities and social services.  At first, Kenny was going to cancel the concert, but the mayor convinced him the show would be a positive step forward for the community.   One good turn, deserves another as KC was surprised by a guest appearance from George Jones  at his Lexington show Saturday night.  The Lexington Herald Leader says everybody in the arena was in on the secret as the Possum strolled onstage during Kenny's "Small Y'All," --a song George had done years ago.  The band then broke into "I Don't Need Your Rockin' Chair,"  and Kenny asked George to stay to perform the classic country ballad, "He Stopped Loving Her Today."   “There’s nothing like sharing the stage with your heroes and when George walked on stage in Lexington it was one of the biggest thrills of my life! He means so much to so many and it meant the world to me that he came to the show,"  Kenny said.  Check it out!   http://www.youtube.com/watch?v=JknDRgWNGLc
