There's good news about the Keith Urban-led "All For The Hall" concert coming up in Nashville. The star-studded show to benefit the Country Music Hall of Fame and Museum sold out in just 20 minutes. And while the show is still a month away, the enthusiastic response has Keith looking ahead: "We are thrilled to announce that we will absolutely be doing this again next year!," he says.

Unfortunately, not all the news is as good. Scalpers reportedly purchased a number of the $25 tickets and are re-selling them at higher prices. Ticket scalping is legal in the state of Tennessee.

Keith's camp issued a statement saying: "We're thrilled with the support we've received from the fans and the artistic community for the 'We're All for the Hall' benefit. We priced tickets at $25 to make the show as accessible to everyone as possible. The issue of ticket scalping cuts across all forms of entertainment and sports and is much bigger than this concert. It's unfortunate that others are choosing to make money from our efforts, but we must remain focused on our stated mission and cannot involve ourselves in a ticket scalping debate or take time or attention away from our message."

Also disappointed with the turn of events is Country Music Hall of Fame director Kyle Young, who tells Nashville's Tennessean newspaper, "As Keith explained on Monday when he announced this show, he understands how bad the economy is, and really wanted these tickets to be affordable for fans. So the fact that tickets may be scalped is disappointing. Unfortunately, it's an all-too-common occurrence and is something that we can't control."

The lineup for the "All for the Hall" concert, which is slated for Oct. 13 at Nashville's Sommet Center, includes Keith, Vince Gill, Faith Hill, Vince Gill, Taylor Swift, Brad Paisley, Jason Aldean and Lady Antebellum, among others.
