UK graffiti virtuoso Banksy has smuggled 500 doctored versions of Paris Hilton's new CD into stores across the country. The CD contain Banksy's remixes and have titles like "Why am I Famous?," "What Have I Done?" and "What Am I For?" His spokeswoman said he had tampered with the CDs in branches of HMV and Virgin as well as independent record stores. He visited cities including Bristol, Brighton, Birmingham, Newcastle, Glasgow and London, she added. A spokesman for HMV said the chain had recovered seven CDs from two Brighton shops but was unaware that other locations were affected... A spokesman for Virgin Megastores said staff were searching for affected CDs but it was proving hard to find them all. "I have to take my hat off - it's a very good stunt," he added.
