Savoy's Roberta Martin, 63, sometimes called "The Dean of Gospel Music," died Jan. 13 in Chicago. She headed her own music school and publishing company there. Many gospel world notables attended the funeral at Mt. Piscagh Church. Savoy, for whom she recorded for 15 years, is putting out a memorial LP this week."
