It was not right of Coleridge in fact it was wrong
(But often we all do wrong)
As the truth is I think he was already stuck
With Kubla Khan.
He was weeping and wailing: I am finished, finished,
I shall never write another word of it,
When along comes the Person from Porlock
And takes the blame for it.
Coleridge’s Person from Porlock had a good few outings in the mid-twentieth-century.
