Apparently some wag in the house of commons wrote a version of that having a pop at Mr Brooon.

"Yesterday upon the stair,
I met a man that wasn't Blair.
He wasn't Blair again today,
I wonder when he'll go away"

I thought you were going to burst into:

I saw a mouse!
Where?
There on the stair
Where on the stair?
Right there!
A little mouse with clogs on going "well I declare" going tip tappity tap on the stair.

Sugar, that is going to be etched on my mind all day now!

Seeing DC in your half awake mind must be more like having a nightmare Deana!

Not the Cheshire Cat then?

This verse, titled "Antigonish" was written by William Hughes Mearns in 1899. William Hughes Mearns, better known as Hughes Mearns (1875-1965) was an American Educator and Poet. He wrote two books which are credited for fueling the educational trend of creative writing. A longer version of this poem, found on en.wikiquote.org starts and ends with the verse you cited but has this verse in between: "When I came home last night at three/The man was waiting there for me/
But when I looked around the hall/I couldn't see him there at all!/Go away, go away, don't you come back any more!/Go away, go away, and please don't slam the door... (slam!)"

The Little Man Who Wasn't There" a song based on "Antigonish" by Harold Adamson with music by Bernie Hanighen

[Lead in to song]
Tex Beneke is whistling (whistlewhistlewhistle)...
Glenn Miller: Hello there, Texas, whatcha say?
Are you whistling in the dark just to scare the ghost away?
Tex Beneke: I know there’s something following me that I can’t see
Someone sure laid an awful hex on me!
Glenn Miller: A hex? Ah, Tex, that’s pretty far-fetched.
Man, I’d say you’re just a little bit tetched!
Tex Beneke: You’d got a load of what I saw last night
You’d pass the Yankee Clipper on its maiden flight!
[Lyrics]
Last night I saw upon the stair
A little man who wasn't there
He wasn't there again today
Oh, how I wish he'd go away...
When I came home last night at three
The man was waiting there for me
But when I looked around the hall
I couldn't see him there at all!
Go away, go away, don't you come back any more!
Go away, go away, and please don't slam the door... (slam!)
Last night I saw upon the stair
A little man who wasn't there
He wasn't there again today
Oh, how I wish he'd go away!
