LONDON -- It's a bird, it's a plane -- no, it's a pig, floating above London.

The 30 foot by 15 foot inflatable porker soared Monday over the derelict Battersea Power station -- an image famous from the cover of Pink Floyd's 1977 album "Animals."

The scene was recreated to mark the release of remastered versions of Pink Floyd's 14 studio albums.

Organizers had hoped to use the original vinyl pig, which has been in storage for about 35 years. But it was found to be leaky, and a replica was created instead.

There was no replay of the moment during the 1976 photo shoot when the original pig broke free of its moorings and floated into the flight path for Heathrow Airport. It was later found in a farmer's field.
