SINGING RAM: Georgia Frontiere is mum these days about her hapless Rams football team and what she’s going to do about it. But that doesn’t mean she won’t stretch her vocal cords in public. . . . Frontiere, a onetime professional singer, will sing the role of the mother in Gian Carlo Menotti’s Christmas opera, “Amahl and the Night Visitors,” this Friday and Saturday at Chapman University in Orange. She mainly confines her singing these days to fund-raising events.
