WORST CONCERT WALKOUTS!

Britney Spears' aptly named Circus tour left a rather sour taste in the mouth of fans in Perth who shelled out for a little Britney magic and got what the WA opposition arts spokesman called a "karaoke session with well-produced videos." Britney's lack of live singing gained the ire of many fans who stormed out before the end "I want my money back or I want her to sing properly,'' one blustered. There was even talk in WA at the time of changing the law to ban entertainers from claiming they were singing live as a result of the Britney debacle.
