When I was a lad ...

James Naughtie said a short time ago on the Today programme on BBC Radio 4:

 

We'll be talking to the commander of a ship that was sunk (in the Falklands War of 1982) who later became First Sea Lord.

 

This little ditty immediately sprang to my mind: 'When I was a lad ...'

 

Now where does that come from?
