Came across a reference to a show id never heard of, The Detectorists, was mildly curious (middle of the night cant sleep moment), so looked for clips or trailers, came across this clip
I dont believe its typical of average shows, but is an interesting and fun digression into history. Other bits were mentioned in an article about the show.
Since I cant hear worth a hoot and like magpies, I looked for a version of the tune above with lyrics
The linked article mentioned a scene Id like to see, something about an outline in the grass as they are leaving a detector location. Looks like episodes can bee seen on youtube and other places.
