The First Amendment guarantees five freedoms: speech, press, religion, assembly and petition. Brad Paisley is grateful for them all, and he's joined forces with 1 for All -- a national program run in conjunction with Nashville's Vanderbilt University -- to tell people how much.

"FREE to play, to sing, to speak, to write," declares an ad featuring the country superstar that ran in Parade magazine. Brad is seen with his trademark paisley Fender Telecaster over his shoulder, singing with his eyes closed and an arm raised triumphantly in the air.

"Thanks to the First Amendment, you can be whoever and whatever you want to be," the caption reads.

Brad joins fellow musicians John Mellencamp and Mary Chapin Carpenter, as well as actor Martin Sheen, in paying tribute to the first 45 words of the Bill of Rights, a document ratified in December 1791.

According to the 1 for All website, the initiative is designed to reinforce the idea that "the First Amendment serves everyone, regardless of faith, race, gender or political leanings. It is truly one amendment for all."

Clearly, when it comes to the this most sacred of U.S. government texts, the 'Remind Me' hitmaker needs no refresher course.

"Freedom is what makes America great," Brad said back in May, when he news of his involvement with 1 for All first broke. "I count myself blessed to live in a country where I can exercise that right every day, whether I'm writing, recording or performing."
