The first Cajun Country Jam at the Livingston Parish Fairgrounds this Fourth of July will give eventgoers a chance to meet the stars of several television shows that were popular decades ago, along with legends of country music.

“It is expected to be the biggest event in Livingston Parish history,” organizer Scott Innes said.

Organizers expect 30,000 to 40,000 people to attend, Innes said, including some flying in from England and other parts of the world to see the Dukes (of Hazzard, of course) and other TV stars.

In addition to the “Dukes of Hazzard” cast, those attending the event include Barbara Eden, who played Jeannie on “I Dream of Jeannie”; Dawn Wells, who played Mary Ann Summers on “Gilligan’s Island”; and Larry Wilcox, who played Officer Jonathan “Jon” Baker on “CHiPS.”

In addition to the TV stars, country music legends Tracy Lawrence and Mark Chesnutt will take the stage. Other bands with scheduled appearances include the Chee-Weez, LeRoux and the River City Good Time Band, to name a few.

The event is slated start at 9 a.m. and end about 10:30 p.m., Innes said, and free parking will be available.

The midway of rides will be open, and those attending the event can ride free after paying an admission fee at the gate and receiving a bracelet, Innes said.

Tickets for the Cajun Country Jam will go on sale Friday at all Carters Supermarkets in Livingston Parish and Ticketmaster. Tickets are $20 in advance or $25 at the gate. On Friday, those who purchase tickets will receive one free ticket for every two tickets they purchase, Innes said.

Gates will open at the fairgrounds at 9 a.m., and those attending are asked to bring their own lawn chairs. No food or drink will be allowed in the gate the day of the event; however, baby formula and products needed for health reasons will be allowed, Innes said.

Food and drink vendors will offer a wide selection of choices throughout the day, as well as a covered area to sit and eat, Innes said.

No pets allowed except service animals.

Cameras are welcome; however, organizers forbid the filming of Lawrence or Chesnutt’s performances.

Event shirts and souvenirs will be for sale.

ATMs will be at the front gate and at the Jefferson Financial tent on the grounds, and cellphone charging stations will be available.

A fireworks show will start after Chesnutt’s show about 8:30 p.m. to 8:45 p.m., Innes said.
