Janis Sharp, mother of self-confessed hacker Gary McKinnon, is trying to organise a sing-in for US president Barack...
Obama to protest the US's continuing demand for her son's extradition to charges related to what US officials have called the greatest military hack in history.
The protest is timed for when Obama visits London for the G20 meeting at the end of March. Sharp has changed the words to former Crosby, Stills, Nash and Young member Graham Nash's "Chicago". She hopes to have the sing-in televised and broadcast internationally.
Sharp has also joined social networking community Twitter. Her first follower was Trudy Styler, wife of Police frontman Sting the couple have lent their support to the campaign against McKinnon's extradition.
