Who Killed Cock Robin?

Promise, this is my last 'memory' song for now. There's a theory that it' s about Robert Walpole. Don't know, but it bears thinking about in any case. Sure as birds' eggs it isn't just a nursery rhyme.. Back tomorrow evening DV and facing the battle that has been joined whilst I was otherwise occupied. God bless and strengthen our biships of the US, UK and Ireland...
