The Rev. Murray Rogers and Raimon Panikkar were intimate friends of Swami Abhishiktananda. Murray Rogers was interviewed by Christian Hackbarth-Johnson and Raimon Panikkar by Gunther Franke for a documentary on Abhishiktananda that was planned for 2010, the one-hundreth anniversary of his birth. Unfortunately, the documentary was not able to be produced, but the videos are now available for public viewing. They have been posted on YouTube and can be accessed with the links given here:
