The Killers frontman Brandon Flowers has traded cigarettes for a herbal remedy - and is surprised he's already reaping the benefits. The MR BRIGHTSIDE rocker has given up smoking on the advice of his doctor, and admits a natural alternative is vastly improving his vocal talents. He says, "I stopped smoking cigarettes recently and a German doctor gave me some kind of camomile concoction that I pour into water, put a towel over my head and breathe it in. "It's good for my voice."
