The actor Philip Stone "Dad" in A Clockwork Orange was a neighbour of ours in W London; though we often spoke, we only spoke about the film once, it was the day after my wife & I had both went to see A Clockwork Orange when it was first re-released in the UK after Kubrick's death.
We were cuing for a bus to Ealing Broadway I told him my wife & I had both seen Kubrick's film in the 70's & again the night before (1999 ish) on our 20 minute journey he told of the great time they had making the film & commented that the turntable was futuristic then. Apparently some actors & crew bought one.
Coincidentally as a 15 year old, Anthony Burgess had come to my school 6th form debating society to talk on George Orwell. After the talk I spoke to Burgess, as I had just read the recently released A Clockwork Orange, he told me that it was written as a cathartic exercise after his wife was sexually assaulted in the 1940's I may well have been one of the first to hear that explanation...
Neither of these stories are HiFi & I have never told these stories other than to my wife, however they are true & may explain some of my affection for the Hydraulic reference...
