I'm sorry that your thread has become derailed because, like you , I love the sight of the sport as shown in the video. However, apart from the fact that shooting that moor was banned in 2018 so the date on the film is questionable, the issues surrounding it are personal. I live just over the western horizon shown in the video and worked on and around the moor for tens of years. A convicted animal rights law breaker called Luke Steele from Ilkley was the driving force behind getting his Marxist followers to relentlessly lobby the labour Council to end shooting there. At a stroke, all aspects of grouse shooting and moor management were wiped out. It may look like a pretty traditional picture in the film, but, this happened just six years ago and to the people concerned the wound is still open. This probably isn't the best place to raise these issues but, to me, the video was more than a traditional/historical shoot image. It was a painful elegy .
Blue Remembered Hills
-----------------------------
Into my heart an air that kills
From yon far country blows:
What are those blue remembered hills,
What spires, what farms are those?

That is the land of lost content,
I see it shining plain,
The happy highways where I went
And cannot come again.

A.E. Housman
