Harry Price engaged in a seance in 1963 specifically to talk with George Woods and Betty Green about ghosts. Price was one of the most influential figures in the early years of ghost research. He was a skilled magician and sought to identify fraud where it manifested itself and separate real ghostly encounters from fabrications (Harry Price the Psychic Detective. Sutton Publishing: 2006). As a result of his interest in ghosts while alive, he apparently felt himself qualified to speak about ghosts now that he had the perspective from the afterlife.
Price explains that there are two categories of "ghostly" manifestations people on Earth experience: (1) etheric memories and (2) Earthbound spirits.
