Country superstar Toby Keith will kick off the Minnesota State Fair grandstand series on Aug. 21. He is the final act announced for this year.

The show will be part of Keith’s Shut Up and Hold On Tour. He’s promoting last year’s “Drinks After Work” album. But he’s a hard worker. Last Saturday, he performed in a pouring rain at the annual Winstock festival in Winsted, Minn.

The Oklahoma maverick has done OK for himself. Last year, Forbes magazine labeled him as country’s $500 million man. In addition to the millions he makes from concerts and recordings, he’s got an endorsement deal with Ford, his own liquor (Wild Shot), a 10 percent interest in Big Machine Records (home to Taylor Swift and Tim McGraw) and a partnership in the I Love This Bar and Grill chain, which includes a place in St. Louis Park.

Keith, known for such hits as “How Do You Like Me Now,” “Beer for My Horses” and “Made in America,” last performed at the State Fair in 2011.

Country’s rap-inclined star Colt Ford will open for Keith on Aug. 21.

Tickets, priced at $59 and $49, will go on sale at 11 a.m. Monday at,, 1-800-514-3849 and the State Fair box office.
