Taste of Country reports that Brad Paisley is the latest celebrity joining the  1 For All national public education campaign. 1 For All is designed to give better understanding to Americans about their freedoms granted by the First Amendment.

Fellow artists and performers Ellen DeGeneres, John Mellencamp, Kesha, and Mary Chapin Carpenter, are showing  support for the campaign by appearing in the national ads as well.

More on 1 For All campaign after the jump.

During that show, Brad gave the audience a taste of his new single, 'Old Alabama'. And sure enough, during the middle of the song, all four members of the group Alabama came on stage to sing along with the song.
