Not really covered the Woodcraft who have been meeting at Hardy Lane since the 1970's, and some earlier activity in the late 1940's and 1950's. It is an area still to be explored. Today was notified of an online video of a 1968 film called I'm a Member of a Family at the Yorkshire Film Archive which documents an international Woodcraft Camp. When you quote "they say the past is a different country they do things differently there" you can see the truism of that phrase. It's the L.P. Hartley's novel The Go-Between to save you looking it up.
Also told it was really like this by a former member back in the 1970's. It's appears as a charming, innocent age set against a background of the Cold War and a call for World Peace. Anyway here is the link to the video (10 minutes, colour, sound). It's http://yfaonline.com/assetDetails.cfm?film=2179
