Recall is rewriting

The recall of memory
Is its rewriting.
Someone has stolen the crown jewels
From my mind.
(I suspect communists)
The magic of the crown I summoned as defence
A symbol of this liberal isle, a defiance
(Liberal as far as the Severn and the Tay)
It's recall is eroded, the thieves have got away.
Now decorated septugenarians
In medieval regalia march in unison, slow
Through the fluted, carved parliamentary halls
With just a velvet cushion to show.
