Charlotte Motor Speedway officials have announced a lineup of special guests, including country music artist Darryl Worley, who will participate in pre-race ceremonies leading up to the Coca-Cola 600 NASCAR Sprint Cup Series event Sunday, May 25, at the 1.5-mile superspeedway.

Worley, whose 9/11-inspired song "Have You Forgotten?" was number one on Billboard's Hot Country Songs chart for seven weeks, will sing the National Anthem prior to the Coca-Cola 600. Since 2000, Worley has recorded five albums and put 15 country singles on the Billboard charts-three of which climbed to the top spot. The singer wrote "Have You Forgotten?" after a USO trip to entertain troops in Afghanistan.

Dr. Robert H. Schuller, founder of the Orange Grove, Calif.-based Crystal Cathedral church, will lead race fans in the Pledge of Allegiance before the Coca-Cola 600. Rev. Schuller should feel right at home addressing an audience in Charlotte Motor Speedway's 1.5-mile oval-he performed his first religious services at the Orange Drive-In Theater in 1955. His weekly Hour of Power television program, which he co-hosts with son Robert A. Schuller, reaches 20 million viewers around the world.

Dr. William K. Thierfelder, president of Belmont Abbey College in Belmont, N.C., will deliver the invocation before the race. The multi-faceted Thierfelder is a licensed psychologist who was a medalist at the 1981 U.S. Track & Field Indoor National Championship, trained as a high-jumper for the 1984 Olympics and is a member of the United States Olympic Committee's Sports Psychology Registry. He has helped more than 100 athletes at the Olympic and professional levels improve their performances.

Tickets for the May 25 Coca-Cola 600 start at $39 and can be purchased online at or by calling the Charlotte Motor Speedway ticket office at 1-800-455-FANS.
