On May 12, CMT's 'One Country' is set to broadcast a special 90-minute concert which will benefit those affected by the recent tornadoes that ripped through multiple southern states last week. Hank Williams Jr., Lady Antebellum, Keith Urban, Tim McGraw, Sara Evans, Alabama, Ronnie Dunn and others are all slated to appear during the concert, which airs on the music network at 9:00PM ET.

"I just couldn't believe what I was seeing on TV," Hank Jr., who contacted CMT to come up with a way to address the tragedy that leveled many towns, says. "Alabama is home ... I am really pumped about helping. I want to raise lot of money, and thanks to my good friends, we are going to be able to make a difference."

All proceeds from the event will benefit the American Red Cross Disaster Relief efforts. Viewers are encouraged to pledge contributions online by clicking here or by texting REDCROSS to 90999 to make a $10 donation.

The concert special will broadcast live from Nashville on Thursday, May 12 and will also be available for streaming online at CMT.com. Additional artists are expected to be announced in the coming days.
