it's nigel planer who kindly let me take his photo as he went about his business.  he's better known as his alter ego neil on the young ones who of course sang 'hole in my shoe'.  My favourite bit ever is around 40 seconds in to this .  the timeless wonder of it: we sow the seed, nature grows the seed etc.   A quick youtube search for 'nigel planer' reveals how many fantastic comedies he's been involved with.
