In the interests of research I wanted to know the size of a delivery van large enough to move the contents of a small cottage. I asked the OH and he said a ten-tonner, so I Googled "Ten ton truck".
The first items that came up began, "There is a light that never goes out." Strange, I thought, that's not what I was after, but I read it anyway.
Apparently there is a song by that name and in the lyrics my research item is mentioned.
I have removed the direct quote because I understand it infringes copyright! There's nothing to stop you looking it up for yourself, and I assure you it mentions a ten ton truck!
It was sung by The Smiths, which in a weird way was appropriate because my book's working title is "The Smith Girls" !
I tried Googling images of "ten ton van" next, and among the pictures of all kinds of vehicles was this face. Why? I thought, so I clicked on it.
He was Ton van Heugten, the Dutch 1981 Side-car-cross World Champion. A nice face but not what I needed.
And besides, the OH was wrong - a ten tonner is too big. My chap in the 1950s drove a smaller vehicle, so I've gone for a four ton van.
Research can lead you in odd directions, can't it?
