MOM’S CORDS? Chastity Bono longs to be more than just Sonny and Cher’s daughter. She now has her own rock band, Ceremony, and a soon-to-be-released album: “Hang Out Your Poetry.” . . . . She performs tonight at the Coach House in San Juan Capistrano. . . . But her handlers say no interviews, please: This is only a warm-up for a later tour. She did prepare a statement: “Sure, some will say they only made a record because she’s Cher’s kid. But we have substance.”
