Johnny Nash, a singer-songwriter, actor and producer who rose from pop crooner to early reggae star to the creator and performer of the million-selling anthem “I Can See Clearly Now,” died Tuesday, his son said. Nash, who had been in declining health, died of natural causes at home in Houston, the city of his birth, his son, Johnny Nash Jr., told The Associated Press. Nash was in his early 30s when “I Can See Clearly Now” topped the charts in 1972 and he had lived several show business lives. Music is for the ears and not the age,” Nash told Cameron Crowe, then writing for Zoo World Magazine, in 1973. He had loved riding horses since childhood and as an adult lived with his family on a ranch in Houston, where for years he also managed rodeo shows at the Johnny Nash Indoor Arena.
