Thanks Geoff, that's really brilliant.

I am organising a week of science and storytelling for 14 year olds. Last year we started with the story of the Mass Trespass on Kinder and sang the Manchester Rambler. This year we will be at Castle Head near Grange over sands. I have just discovered it was the home of John 'Iron mad' Wilkinson. That's why I need a song or two to kick of the week. Thanks again
