The BBC came under fire for a decision not to air a song, which has hit top of the charts after the death of former British Prime Minister Margaret Thatcher, in its weekly music countdown show.The song, \"Ding Dong! The witch is dead\" from the 1939 movie The Wizard of Oz, is now contending to gain the top slot in Britain\'s weekly list of the top 40 best-selling singles that are usually played in full on a BBC Radio 1 chart show on Sunday, press tv reported.However, the BBC has announced it will only air a 5-second clip of the 51 second song in the form of a news broadcast, with the BBC director Tony Hall saying the \"tasteless\" and inappropriate song may offend Thatcher\'s supporters while banning it may lead to public outrage.Thatcher\'s death on Monday led to a hail of \"Thatcher death parties\" on the streets of different cities across Britain including Glasgow, London, Belfast and Manchester.The protesters also took to the internet to voice their pleasure at the 87-year-old ex-PM\'s death, with the word \"witch\" becoming a rally point for her opponents both on the web and on the streets.
