After scoring hits for Bollywood and southern films, which have won lakhs of admirers around the world, music composer A R Rahman has now written an 'anthem' on the theme of eradicating poverty.

The song, titled Cry For Me, Brother is very close to his heart, said the 39-year-old Rahman, who was in Delhi [Images] for a concert, where he rendered the song. "The anthem isn't just music, but a wake-up call to end poverty," he said.

The composer, who is also the international ambassador of the anti-tuberculosis campaign, 'Stop TB', visited a slum cluster in Mangolpuri in west Delhi, where he interacted with patients suffering from the disease. "One third of the people who die in the world of TB are Indians and this pains me," he said.

Applauding Sangharsh, the citizen's initiative to battle TB in the slum cluster, Rahman said, "This has set an example for the whole of India and I want to take it to other places."

After interacting with social workers, Rahman agreed that though treatment procedures like DOTS exist, a lot still needs to be done to create awareness about the disease.
