The lineup has been announced for the fourth annual Johnny Cash Music Festival, and some of country music's biggest stars will be joining in the celebration.

Reba McEntire, Loretta Lynn and Bobby Bare will all appear at the event, along with comedian and gospel singer Mark Lowry, who will serve as the evening's host.

“If we had any one of these four individuals on the bill, we would have an extremely successful event,” producer and festival founder Bill Carter says. “The reputation of the event and generosity of the people at Arkansas State and in Jonesboro continue to grow each year.”

McEntire says she was honored to be invited to participate in the meaningful show.

“When I was asked to perform at the Johnny Cash Music Festival, there was absolutely no hesitation,” McEntire notes. ”I have always had a great deal of respect for Johnny Cash, and not just because he was one of the finest entertainers, performers and recording artists this industry has ever known. It is also because of his compassion and generosity."

She feels Cash himself would have approved of the event. "The fact that some of the money raised from these concerts goes into a scholarship fund to help deserving kids further their education is something I know would make him very proud," she continues. "I’m also really happy that I will be playing on the campus of Arkansas State again -- we had a great time when I performed there years ago. Jonesboro is a very hospitable town, and I look forward to being there again.”

The Johnny Cash Music Festival will be held on August 15 at Arkansas State University in Jonesboro, Ark. Proceeds from the concert support both the restoration of Cash's childhood home in Dyess, Ark., as well as a scholarship fund.

Tickets will go on sale on Feb. 28 and are available for purchase here.
