The star-studded concert celebrating the music of all-time great country-singer George Jones keeps adding more stars. Artists newly added to that show, titled “Still Playin’ Possum,” a reference to Jones’ nickname, include: Aaron Lewis, Blackberry Smoke frontman Charlie Starr, Dillon Carmichael, Gretchen Wilson, Joe Nichols, Sara Evans, and Randy Travis.

Set for April 25 at the Propst Arena at Huntsville, Alabama’s Von Braun Center, the jaw-dropping lineup already was packed with Wynonna, Brad Paisley, Dierks Bentley, Jamey Johnson, Justin Moore, Lorrie Morgan, Mark Chesnutt, Michael Ray, Sam Moore, Tanya Tucker, Trace Adkins, Tracy Byrd, Tracy Lawrence and Travis Tritt.

Jones was a gifted country balladeer with a stirring voice. The Texas native’s classic hits include “She Thinks I Still Care,” “The Grand Tour,” “Tender Years” and heartbreaker supreme “He Stopped Loving Her Today.”

Tickets to the concert, being filmed for TV broadcast at a later date and channel yet to be name, quickly sold out. But after the lavish red-curtain-dappled stage was designed, that layout freed up some floor space.

Some 300 additional tickets will be released 10 a.m. today via Ticketmaster and the Von Braun Center Box Office, located at 700 Monroe St. Prices for this batch haven’t been released but the initial release started at $25 on up, plus fees.

The “Still Playin’ Possum” concert takes place 10 years after Jones died, at age 81. At the show, each artist will cover two of Jones’ songs onstage. For example, Wynonna and Jamey Johnson will sing “Golden Ring,” Jones’ powerful duet with Tammy Wynette, who Jones was married to at one point.

Jones’ widow, Nancy Jones, who was married to Jones for more than 30 years, is executive producer of the concert. She personally called the acts to see if they’d be interested in paying musical tribute to her late husband.

Asked what George might think of such an epic tribute to his music, Nancy says, “He’s probably up there sayin, ‘Honey, I can’t believe all those people love me that much.’”

Nancy says her excitement continues to build as the concert nears. “Who would have thought we would get this many artists?” she told AL.com Wednesday via phone. “That’s a formidable lineup. Twenty-plus, and more and more every day.”

She’s particularly excited Lewis was added to the show. “George and Aaron did a song together, ‘Country Boy,’” Nancy says. “He just fell in love with Aaron when they went into the studio, so I’m thrilled that he has jumped in.”

One of the reasons Huntsville’s Von Braun Center was picked for the concert was Jones was set to perform at that venue as part of his farewell tour before his 2013 passing. Plus, the Jones’ were fond of Huntsville, where the singer performed several concerts over his career.

An available $200 VIP upgrade for “Still Playin’ Possum” includes dinner the night before the George Jones celebration concert with Nancy Jones and special guests including Randy Travis. In other George Jones news, Nancy will publish a yet-to-be-titled book on Sept. 12. She says the book will be about “my life with George Jones. And the truth.”
