One misty, moisty morning

One misty, moisty morning,
When cloudy was the weather,
There I met an old man
All clothed in leather

All clothed in leather,
With a cap under his chin.
How do you do?
And how do you do?
And how do you do again?

To make it clear, I met no men clothed in leather this morning - but I did remember this old nursery rhyme when I saw this. No one in here has heard of it!

Blackford Hill of course. The radio transmitter - providing microwave links and support for emergency services - appears quite ghostly in the morning gloom.
