I called KISS and they do not know. If they don't then nobody does.
But this is what they do know...The concert gates open at 8:30am and the concert begins at approximately 10am. The scheduled lineup is tentative and subject to change but is as follows: Sawyer Brown along with XXXXX XXXXX, XXXXXyn Dawn Johnson, Phil Stacey and Rissi Palmer, Taylor Swift, Joe Nichols Gretchen Wilson, and Big & Rich.
Hope that helps.
