Fred Dibnah How to climb a chimney overhang at 50+

I stumbled across this guy on YouTube. I remember watching him on TV when I was a child. Filmed well before the days of safety harnesses and obsessive safety culture, it just seems and was a different age back then. Talking of a different age just look at the magnificent stone work on what is after all just a chimney. The pride people took in their work must have been immense. I also cant get over the scale of this structure either. I wonder if its still standing ? Fred Dibnah was a national treasure.
