Correction, Sword beach. 41 Commando probably was close to Oboe, as they were tasked with landing sort of in the area between Juno and Sword, and Oboe was the most Western sector. Ken did an interview as well with the BBC back in 2014 regarding his DDay landing that's on YT if you search for it, as well was written about in the book WW2: The Last War Heroes from DDay to Berlin. You can tell from the BBC interview to his most recent, that his speech has declined rapidly. He's still pretty sharp though, and again, if anyone is writing, reading, researching, or just interested in Dunkirk/DDay operations, as well as the Atlantic convoy missions, Ken is enthusiastic about speaking to anyone about his experiences still.
It won't be long before all we'll have is what is recorded and written down from our WW2 vets.
