Willie and Korie Robertson will discuss their show, their daily lives and will also take questions from fans, said Carey Howell, superintendent of the grandstand. The talk format is something “more and more fairs are looking into, rather than just having bands,” he said.

Tickets will most likely go on sale in late July or early August, Carey Howell said. Pricing has yet to be determined. ZZ Top tickets will also go on sale around the same time.

The Robertsons have been doing shows at various fairs and are scheduled to make a similar appearance at the Iowa State Fair in August, with fellow Uncle Si Robertson. Tickets for that show, A Conversation with the Robertsons, are $32, according to the Iowa fair’s website.
