鈥淧ussy cat, pussy cat, where have you been?
I鈥檝e been up to London to look at the Queen.鈥
Only this time, it was the Queen who made the journey to look at - or, more accurately, grant an audience to - Scotland鈥檚 new first minister, Alex Salmond.
Her Majesty is in Holyrood (Palace not Parliament) this evening for the event.
Mr Salmond popped down the hill from St Andrews House.
The British regal State has had to absorb a few shocks down the centuries.
Think of this one: The Queen is meeting a head of (devolved) government who is committed to ending the Union between Scotland and England.
The political Union, mind. It is the 1707 Treaty that would be repealed.
Alex Salmond has taken considerable pains to stress that the SNP would sustain the regal Union of 1603 - when King James VI of Scotland ascended the English throne.
Still, Scottish self-government and monarchy have had their tense moments.
In 1977, during her Silver Jubilee, the Queen stressed the benefits of Union.
Remember this was in the run-up to proposed devolution in Scotland and Wales.
Acknowledging her Scots, Welsh and English antecedents, Her Majesty continued: 鈥淚 cannot forget that I was crowned Queen of the United Kingdom of Great Britain and Northern Ireland."
That was interpreted, rightly, as a sentiment of disquiet with devolution.
Much later, after the Scottish Parliament had finally arrived, Her Majesty was to speak with approval of the 鈥渦nity based on diversity鈥 which devolution represented.
That鈥檚 called adapting to circumstance.
Still, though, it was in the context of 鈥渟trengthening the bonds鈥 within the UK.
Alex Salmond brings a new dimension. He wants, he says, to sustain and strengthen the 鈥渟ocial union鈥 between Scotland and England.
He defends the regal union. But he wants, ultimately, to end the political union, to repeal the Act of Union.
Addressing the General Assembly of the Church of Scotland last week, the Duke of York, the Queen鈥檚 second son, said that the election of an SNP government had 鈥渞attled the timbers鈥 of the Union.
Mr Salmond said these were 鈥済ood natured remarks.鈥
Maybe so - but you can bet that events in Scotland are being assessed extremely carefully in terms of their impact on both the political and the regal union.
PS: A newspaper diary suggested that Alex Salmond had demonstrated a rebellious streak by merely nodding - instead of speaking - when the Loyal Oath was adminstered in the Court of Session as he became FM.
Sorry and all that - but the participants in such Court ceremonies only ever nod.
They have done so down the decades.
Alex Salmond wasn鈥檛 rebelling: He was complying.
