Your free country music show for Derby Week will be Clay Walker with J. D. Shelburne at 4th Street Live! on May 3. Walker, as fans are well aware, is the country music face of multiple sclerosis, which he has. Medication keeps the disease at bay and he continues to record and tour. While he had his greatest success in the Nineties (his last #1 hit was 1997's "Rumor Has It"), he continues to chart, with the title tune from his 2009 album She Won't Be Lonely Long reaching #3 on the Billboard Country chart. His opening act, J. D. Shelburne, is sure to be urging all his fans to come see him, after his Headliners show was canceled due to a certain basketball game. It should result in a packed street under the glass.
