I guess it was the Philip Dore. An old LP (1971) of mine states that he was organ scholar of Queen's College, Cambridge, city organist at Portsmouth, organist of Mullingar Cathedral, Lecturer in Music at University College, Dublin. He was also on the music staff at Christ's Hospital, Horsham, and Brighton College, and later at Ampleforth College. He looks a bit ancient on the photo of him on the LP sleeve, and his playing seems to be rather influenced by advancing years.
