The wife of Grand Ole Opry star Little Jimmy Dickens, touched by a newspaper story, went down to the Coffee County, Tenn., jail and put up $2,500 for a mother of two young children who had been jailed for 99 days because she couldn't make bail. Mona Dickens showed up Wednesday night in a black limousine and brought out Lydia Roberts, 36, who is charged with writing worthless checks, for a tearful reunion with her family.
