|Cee Lo Green is doing his bit to help US volunteer firefighters.
The singer-songwriter is recording Thank You, another rewrite of his hit song that's known in its PG-rated version as Forget You, to publicise a battery donation campaign.
"I believe I can contribute a great deal more than mere entertainment," he said. Cee Lo is helping to promote Duracell's battery donation drive for volunteer fire departments in the States.
The firefighters use the batteries for flashlights and other equipment. In the US, the firm is donating one battery for every specially marked pack of batteries customers buy.
Cee Lo's mother was pulled by volunteer firefighters from a serious car wreck, and had served as a firefighter herself.
"I always wanted to be a fireman, like a lot of kids," he said.
"There are quite a few heroes out there," he added.
Cee-Lo, who is touring Europe, has been involved in a number of other charitable efforts, including plans to donate proceeds from his song It's OK to Japan's earthquake relief.
