Skip Young, who appeared in the television series “The Adventures of Ozzie & Harriet” as Wally, a buddy of the Nelson brothers, died at his home. He was 63.Young was found by family members Wednesday morning, according to San Bernardino County deputy coroner Linda Myers. The cause of death was undetermined pending a medical report, but it appeared to be natural causes, she said. Young, who was born Ronald Plumstead, played the character of Wally Plumstead from 1957-66 on the ABC series. It starred real-life couple Ozzie and Harriet Nelson and their sons, David and Ricky. In the show, the Nelson clan would rescue Wally from misadventures such as schemes involving women college students. “He was jovial, lovable, he was that kind of imp,” said his friend Buck Buchanan, who played a neighborhood kid on the show. “If he had been born earlier, he would have been Spanky McFarland. He always had a joke and he was always laughing. He was a very nice man.” “Ozzie and Harriet,” one of TV’s longest-running family comedies, first appeared on TV in 1952 after eight years on radio. The show ended in 1966, but reruns are still seen in syndication. A memorial service will be held at 11 a.m. tomorrow at Our Lady of the Desert Catholic Church in Apple Valley.
