The general socio-political fallout of Iraq War also extended to popular music. In July 2002, the release of English musician George Michael's song "Shoot the Dog" proved to be controversial. It was critical of George W. Bush and Tony Blair in the lead up to the 2003 invasion of Iraq. The video showed a cartoon version of Michael astride a nuclear missile in the Middle East and Tony and Cherie Blair in bed with President Bush. The Dixie Chicks are an American country music band. During a London concert ten days before the 2003 invasion of Iraq, lead vocalist Maines said, "we don't want this war, this violence, and we're ashamed that the President of the United States [George W. Bush] is from Texas". The positive reaction to this statement from the British audience contrasted with the boycotts that ensued in the U.S., where "the band was assaulted by talk-show conservatives", while their albums were discarded in public protest. The original music video for the title song from American pop singer Madonna's "American Life" album was banned as music television stations thought that the video, featuring violence and war imagery, would be deemed unpatriotic since America was then at war with Iraq. She also made her widely considered "comeback" album with her tenth studio album Confessions on a Dance Floor which topped the charts worldwide in a record 40 countries. As of 2016 the album has sold more than 11 million copies worldwide. Madonna also made history by completing her Sticky &amp; Sweet Tour which became the highest-grossing tour by a female artist and the tenth highest-grossing tour by an artist during 2008–2009.
