It took a very early start, 12 canisters of gas and some careful manoeuvres to recreate one of British rock music's most enduring images.br Throw into the mix an inflatable pig the size of a bus above London's Battersea Power Station, and you have a recreation of Pink Floyd's Animals album cover -- 35 years on from the original shoot -- and restaged to mark the reissue of the band's back catalogue.br The original photographer Howard Bartrop was just twenty-three years old in December 1976 and on one of his first professional assignments.br SOUNDBITE: Photographer, Howard Bartrop, saying (English):br "It was quite tricky that day and very cold and of course famously after a day or so we had the problem where he floated up away from the building and was spotted by commercial pilots landing into Heathrow. He then floated off towards Kent, followed by a police helicopter, landed in a farm I believe and frightened all the cattle. Basically he was retrieved, patched up and put back in the air the next day so we could try and photograph him again."br Record bosses had to commission a new exact replica inflatable pig for the stunt because the original cover star was found to be leaky.br But such a minor detail didn't stop the die hard Pink Floyd fans like 49-year-old Julia Kleemann from Perth in Western Australia getting up at first light to see history re-createdbr SOUNDBITE: Pink Floyd fan, Julia Kleemann, saying (English):br "When I was growing up this album I just loved it. I just can't get enough of this, even to this day I think this is just wonderful for me."br Pink Floyd's 14 studio albums have been remastered and are now available on CD.br Edward Baran, Reuters, London.
