DIED. CONWAY TWITTY, 59, country music singer; in Springfield, Missouri. His given name was Harold Jenkins, and he started off as a rock 'n' roller. He wasn't the handsomest guy in the world, and he didn't have the greatest voice. Nonetheless Conway Twitty became one of the most popular country stars ever and a canny manager of his career. His lyrics said the things women want to hear and men wish they could say. His hits included It's Only Make Believe, Hello Darlin' and numerous duets with Loretta Lynn. "It's 99% the song, not what I do," Twitty once said. He played the percentages and came out a winner.
