Willie Nelson's cherished chairty event, Farm Aid, has added another country superstar to the lineup. Kenny Chesney will perform at the event, which takes place Sept. 22 at Hersheypark Stadium in Hershey, Pa. The "Come Over" singer last took the Farm Aid stage for its 25th anniversary concert in 2010.

"Growing up in a small town outside Knoxville, family farmers were a big part of our community," says the Luttrell, Tenn., native. "I am proud to play on the Farm Aid stage again, especially in Central Pennsylvania, where agriculture is at the heart of the community."

Onstage, Kenny will join Farm Aid board members Willie, Dave Matthews, Neil Young and John Mellencamp , in addition to Jack Johnson, ALO, Pegi Young and the Survivors, and Lukas Nelson and Promise of the Real.

"The charity that drives Farm Aid is so impossible to argue against," Matthews says, adding that Farm Aid's mission is "to give voice to the plight of the family farmers in this country, to give voice to people who are voiceless but are so essential to how we identify ourselves, and speak the truth in a public way."

Tickets for the star-studded concert are available now at LiveNation.com, TicketMaster.com, GIANT Center Box Office or by calling 800-745-3000. Tickets range in price from $35.75 to $99.75.
