Brad Paisley has always had a soft spot for Alabama – both the band and the state – and now he's coming to the aid of people in the south who have had their lives turned upside down by the devastating tornados there. Brad has decided to donate all his artist royalties from the digital singles sales from his current hit song, "Old Alabama," to tornado relief via the American Red Cross.

"When I first started playing music, if you didn't cover an Alabama song in your set, you might as well go home," he tells People.com

When the Paisley wrote the song, he had no idea how timely it would be. In fact, he meant it as a tribute to the iconic superstar country-rock band Alabama.

Now, Brad is doing what he can to help the band's home state get back on its feet. On Tuesday night, the band performed "Old Alabama" at the Grand Ole Opry with Paisley as part of the commemoration of the one-year anniversary of the Nashville flood.

"Old Alabama" is the second single from Paisley's forthcoming album, This Is Country Music, to be released May 23.

You can download the song - Old Alabama - on itunes now.
