A few of the performers in the 90-minute live concert special are Hank Williams Jr., Tim McGraw, Keith Urban, Lady Antebellum, Ronnie Dunn, Sara Evans, Alan Jackson, Trace Adkins and Little Big Town.

ESPN reporter Erin Andrews, Headline News anchor Robin Meade and comedian Ron White join the benefit as co-hosts.

The concert will assist the victims of the numerous devastating tornadoes that raged through seven states in the south last month, including the hardest hit, Alabama, killing 329 people and literally destroying countless businesses, schools and homes. All proceeds will benefit the American Red Cross Disaster Relief efforts.

Alabama native Hank Williams, Jr. originally talked about doing a concert to raise funds.  He later took the conversation to CMT in order to spread the message and help more people.   The tornadoes that struck the south was the second largest outbreak of twisters in United States history.
