One of the most influential rock music groups of all time - Pink Floyd has again in a stunt designed to mark the reissue of  their 14 studio albums floated a large pig above London's Battersea Power Station. The inflatable pink pig, measuring 30 feet long and 15 feet high, was inflated with helium at sunrise for the event, held 35 years after the making of the album cover for "Animals" featuring a similar flying pig.
