Anti-Thatcher protesters react to the death of former British Prime Minister as they gather at Trafalgar Square in London, Monday, April 8, 2013. Opponents of the late Margaret Thatcher are taking a kind of musical revenge on the former prime minister, pushing the song 'Ding Dong! The Witch is Dead' up the British charts in a posthumous protest over her polarizing policies. By Friday, April 12, 2013, the online campaign had propelled the 'Wizard of Oz' song to No. 1 on British iTunes and into the top five of the music chart used by the BBC to compile its weekly radio countdown. The unusual campaign has caused a headache for the BBC. With the ditty near the top of the charts, the broadcaster faced the prospect of airing the words 'The Wicked Witch is Dead!' on its Sunday countdown show, just days before Thatcher's funeral, scheduled for Wednesday.
