In a surprise move, the Dixie Chicks have announced a rare public appearance. The Texas trio have been confirmed as the new Saturday night headlining act for the 2013 Craven Country Jamboree, which takes place from July 11-14 in Craven, Saskatchewan.

The move comes after Lady Antebellum dropped out of their planned appearance because of Hillary Scott's pregnancy. Festival organizers knew they had a big job to replace such an important hole in the schedule.

"We knew we had to find something extra special to replace Lady Antebellum when the band canceled their summer dates due to Hilary Scott's pregnancy," Kim Blevins, Director of Marketing for the festival, says in a press release. "We are extremely excited that we can offer a taste of country music royalty to the Craven Country Jamboree. And it won't be a regular show -- not only will our fans see Natalie Maines, Martie Maguire and Emily Robison, the three original members, this is a greatest hits package. The Craven date will be one of the only opportunities fans of the band will have to see them live. This is an incredibly special moment for Chicks fans and the Craven Country Jamboree."

The Dixie Chicks are the best-selling female act of all time across all genres, with hits including 'Wide Open Spaces,' 'Ready to Run' and 'Cowboy Take Me Away.' They join a lineup that includes Kenny Chesney and Tim McGraw, Scotty McCreery, Phil Vassar, Brantley Gilbert, Doc Walker, Sawyer Brown, Chad Brownlee, Gloriana, High Valley, Small Town Pistols, Jason Blaine, Randy Travis and Bill Anderson.

Tickets are available for $159 at the festival's website, or by calling 1-866-388-0007.
