You have to admire country performers you hear on Big Frog 104 - they're always ready to pitch in during national disasters. Now, a number of country stars are taking part in a concert to benefit those who were ravaged by recent tornadoes.

"Keith Urban, Lady Antebellum, Tim McGraw, Sara Evans, Ronnie Dunn and Alabama are among the first stars to sign on for a CMT benefit concert to help the victims of last week's tornadoes. The 90-minute show was spearheaded by Hank Williams Jr., who went to the channel with the idea. He says, "Alabama is home ... I am really pumped about helping. I want to raise a lot of money, and thanks to my good friends, we are going to be able to make a difference."

The show will air on May 12th on CMT and CMT.com at 9 p.m. [ET]. Proceeds will go to the American Red Cross Disaster Relief Fund.
