http://www.telegraph.co.uk/news/ukn...over-John-Lennons-Happy-Xmas-War-is-Over.html A man has been sentenced for knocking out his sister's two front teeth in a row over a Christmas record 40 years ago. Patrick and Anita Ackroyd disagreed over John Lennon's Happy Xmas (War is Over) when they were teenagers in December 1975. A court heard that he punched her in the face and knocked out her teeth in an assault that has left her wearing a dental plate ever since. Leeds Crown Court heard that Ackroyd and his sister were told by their mother to lie about what had happened and Anita told a hospital she had had an accident. But the truth emerged decades later as police investigated an unrelated and undisclosed matter.
