NEW DELHI — Singer-songwriter Rabbi Shergill is working on a song of outrage against the gang-rape of a 23-year-old student in New Delhi. Shergill, who had joined protestors against the Dec. 16 gang-rape incident which appalled India, said the incident shook his conscience. “I received a sort of poem from someone on this issue, which carries a lot of anger and anguish.” he told the Indian Express. “I have already put it into lyrics and now trying to compose the music. It should be out very soon. Through my music I'll do whatever is possible to heal these wounds,” said the 39-year-old singer of “Bulla ki Jaana” fame. — Agencies
