I caught the back end of a Radio 4 programme last night, it was something about sounds which instantly take you back to another time. There was a woman saying that the sound of an old push along lawnmower takes her back to memories of her father in the garden when she was a very young child and he was only about 25. I thought – how strange to remember your dad being just 25, my first memories of my dad, he must have been around 40, and that was old in the 1960s.

Anyway, when they played the sound of an old lawnmower, so much nicer than the violent noise of a Flymo, I was back in my childhood garden where I spent plenty of time cutting the grass, I could almost see and feel that big circular dip in the middle where the ground had sunk, presumably a previous gardener had had a round flowerbed there.

By coincidence Chris Evans played the original 1960s Doctor Who music on the radio early this morning. I knew that the music had been re-arranged a few times over the years, but I thought that it was just age which had sort of inured me to that sound. It doesn’t seem nearly so scary now, however when I heard the 1960s version it all came back, if I hadn’t already been under the covers, I would have just about been hiding behind a sofa, my usual position when Doctor Who started! Have a listen, I think the first version is by far the most menacing one. What do you think? I am just old enough to be able to remember all of the Doctors.
