Luke Bryan is a lifelong NASCAR fan and has been a part of many NASCAR races over the last several years.

Fans had a chance to see Bryan perform in a pre-race concert at the Daytona 500 back in February and now he will serve as co-Grand Marshall for today's FedEx 400 benefiting Autism Speaks NASCAR Sprint Cup Series race at Dover International Speedway. Bryan is being joined by Joey Principe, a 17-year-old with Asperger’s Syndrome. Asperger's is a high functioning form of autism.

Bryan is currently on his "That’s My Kind of Night Tour” playing across the U.S. and Canada. A few days ago (May 29) he fell off the stage during his show in Charlotte, North Carolina. Although a little scraped up Bryan was okay and the show went on. He continues his tour this weekend with stops last night in Bristow, Virginia and tonight in Holmdel, New Jersey.

In between, he will squeeze in a quick side trip to Dover International Speedway this afternoon to issue the command to start engines and watch his pals Brad Keselowski, Dale Earnhardt Jr. and Jimmie Johnson. Keselowski will start from the pole. Last week's winner Jimmie Johnson is an eight-time winner at Dover's Monster Mile and will start fourth.  Dale Earnhardt Jr. starts 13th. Here is the starting lineup for today's race.
