An apparently lifeless John Lennon lies on the ground, his fellow-Beatles by his side. The haunting picture was taken in 1968 - 12 years before Lennon was gunned down by a crazed fan, Mark Chapman, in New York City. It was one of many images taken by society photographer Tom Murray during the Fab Four's last official photoshoot in 1968, which lay forgotten in an envelope for decades. It was among a number of photographs which were made public today after lying forgotten about for years. 'From two rolls of film there are 23 surviving shots. The colours are astonishing and it's basically because the original slides were kept in the dark in an envelope for so many years.'
