Thank you so much for the link to Youtube. I hadn't heard this, although Stuart Marson's LP Night Falls On The Orchestra has long been a favourite of mine. He did 15 minutes of radio in the 70s, which I taped and then spent years asking about him at festivals, until someone at Wath On Dearne was able to fill me in. I think Stuart was a geography teacher, cos if you Google him, you get a geography text book come up.
