In addition to the November 14 show, which was originally intended as a thank you for WalMart employees, the singer will now be performing November 5-12.

Tickets for the first show went on sale October 6. Overwhelming demand prompted Brooks to add first one more show, then another and another until obligations prevented him from adding more.

When asked about the impressive ticket sales, the singer responded, “For the first time in my life I’m speechless.”
