Judy Garland's song Ding Dong the Witch is Dead, made famous in The Wizard of Oz, has rocketed up the charts on digital retailers iTunes and Amazon in the U.K. as scores of Britons celebrated the death of divisive former Prime Minister Margaret Thatcher on Monday (08Apr13). Elvis Costello's Tramp the Dirt Down, a direct criticism of the former Conservative leader, also entered the top 100 downloads on iTunes.
