I can now add that my stranger on a bench above turned out not to be so much of a stranger after all

When I came home and looked at the photos, I thought he looked rather familiar. I've now confirmed that he is the famous Danish film maker, author and not least Tour de France commentator through nearly 20 years, Jørgen Leth, whose voice I've had a crush on for years. If only I'd known... But I'm in a different world when I'm behind the camera!
