There are Youtube interviews with some of scientists present at Scole sessions, including Rupert Sheldrake, Ivor Grattin-Guinness, and (possibly?) Russell Targ, who attended one of the Hollywood sessions. Robin Foy's must-have journal of the details of every sitting, including witnesses, is published as: Witnessing the Impossible: The Only Complete and Accurate Eyewitness Account of the amazing Physical Psychic Phenomena experienced at Scole, Norfolk, UK and Overseas during the Scole Experiment: 1992-1998
