Dixie Chicks documentary to clash with elections

New Dixie Chicks documentary Shut Up and Sing is set to send shockwaves through the American political arena as its planned release date is just before the November US elections.

The highly-charged film refers to the widespread backlash of fans of US President George W Bush against singer Natalie Maines, after her 2003 statement that the band were "ashamed the president of the United States is from Texas".
