A huge beach party to honor late Queen frontman Freddie Mercury must be stopped because the Zanzibar-born rock star was gay, a Muslim leader said Thursday. Mercury, who died of AIDS in 1991, violated Islam with his flamboyant lifestyle, said Azan Khalid of Zanzibar's Association for Islamic Mobilization and Propagation. "That's why he was branded a Queen," Khalid said, adding that anything linking Mercury with Zanzibar's Muslim population would be offensive.
