It's not too often that a Grammy-winning song gets completely overhauled for a national campaign, but [artist id="1163841"]Cee Lo Green[/artist] has done just that with "Forget You" -- and it's all for a good cause.

The R&B crooner teamed up with Duracell's "Power of Those Who Protect Us" program to benefit the National Volunteer Fire Council, a nonprofit group representing the interests of volunteer fire, EMS and rescue services. The new tune, renamed "Thank You," is available for free download via Duracell's Facebook page.

Not only is Cee Lo hoping to raise awareness for America's volunteer firefighters, but it's a cause that hits close to home.

"It's a very noble cause, and I connect with it very, very personally because my mother was a fireman as well -- one of the first black female firemen in Atlanta, Georgia, so quite a historic accomplishment," Green said.

Of course The Lady Killer was tasked with cleaning up his decidedly dirty lyrics from the original song for this tribute. The new chorus begins: "For a lifetime of service in the name of love, we wanna thank you/ I could say it a thousand times and it wouldn't be enough, we wanna thank you for everything you do."

Green, who is currently [article id="1661361"]a coach on NBC's "The Voice,"[/article] said this campaign capitalizes on the current success of "Forget You."

"It's definitely at the height of a popularity, you know, just kind of unparalleled, and so it's a convenient means of kind of making use of it and using that same spotlight to acknowledge and expose what a great humanitarian cause this is," he told MTV News. "For so many people, citizens to volunteer themselves -- so this is voluntary action. It's not by force, it's not by draft. This is heart and soul, and we appreciate that."
