Livingston Parish’s July 4 Cajun Country Jam, in its second year, began as an idea in radio personality Scott Innes’ head.

“It started smaller last year,” Innes said, with attendance ranging from 2,000 to 5,000 people.

“That was with Restless Heart. This year, we’ve got Tracy Lawrence and Mark Chestnutt performing and for a $20 price tag. You can’t beat that,” he said, adding that keeping the low cost for attendees was the appeal of putting on a show at the fair grounds in Livingston Parish.

He is hoping to see attendance reach closer to 10,000 at this year’s event, which will include a “Dukes of Hazzard” cast mini-reunion and more than 60 replicas of the General Lee, the car featured on the show.

Catherine Bach, who played Daisy Duke; Tom Wopat, who played Luke Duke; and John Schneider, who played Bo Duke, will participate, Innes said, as well as Sonny Shroyer, who played Enos; Rick Hurst, who played Cletus Hogg; and Don Pedro Colley, who played Sheriff Little.

Innes hadn’t planned on bringing the cast back for a second year, “but people kept asking me about it — it was a very popular event — so I decided to ask them to participate again this year,” he said.

After that, ideas just started piling onto the show’s plans. The lineup includes Dawn Wells, who played Mary Ann on “Gilligan’s Island”; Erik Estrada, who played Ponch, and Larry Wilcox, who played John, from “CHiPS”; and Barbara Eden, of “I Dream of Jeannie.”

“It’s sort of a Heinz 57 of ideas. We figured if we’re going to have people out there all day, we need to do something for the kids, so it became sort of a fair-type event,” he said, and ideas are still being added.

“We just added a hot dog eating contest and a dunking booth. There will be something for the whole family to do,” he said.

Advance tickets are $20 and available at Carter’s locations and www.ticketmaster.com. Tickets are not available through Carter’s website, Innes said. Tickets are $25 purchased at the gate.

Paid admission gives patrons access to all fair rides, but a few vendors will have special rides that will cost extra, according to the website.

There is no charge to stand in line and meet the stars, though they will charge a fee for an autograph and pictures.

ATMs will be available at the Livingston Fair Grounds, 13325 Florida Blvd., Livingston.

Children younger than 2 get in free, Innes said.
