Pop singer George Michael has been restricted from serving his community service at the AIDS charity Project Angel Food, based on a recommendation by the Volunteer Center of Los Angeles to the Beverly Hills judge handling his case. Local news stations reported Monday that Michael, who was convicted of lewd conduct in May, now will perform his service by phoning schools and other community centers promoting AIDS awareness. "Judge Rubin, I remain at your mercy," Michael said in a prepared statement Monday. "Please don't let this unusual opportunity go to waste." He added that he didn't think making phone calls to organizations would have the same impact as caring directly for the sick and dying.
