Nursery Rhymes contain so much political commentary of the times in which they became popular, that the history behind them is often more fascinating for the adult.
There are many versions of this rhyme, all with reference to the valued leather clothing.
One misty moisty morning, when cloudy was the weather, I met a withered old man a-clothed all in leather, He was clothed all in leather with a cap beneath his chin, singin': "How d' you do and how d' you do and how d' you do again"
It could be argued that today's commentary is not so creative or is it?!
