Analysis of Who is Kator Anyhow?

Why, oh why was Kater lifted
From the darkness, where he drifted
All unknown, and raised to honour,
Side by side with Dick O'connor,
In the Council, free from row?
Who is Kater, anyhow?
Did he lend our armies rally,
Like the recent Billy Dalley?
Did he lend a Premier money,
Like -- (No libels here, my sonny. -- Ed. B.)
Was he, like John Davies, found
Very useful underground?

Not at all! his claim to glory
Rests on quite another story.
All obscure he might have tarried,
But he managed to get married --
And (to cut the matter shorter)
Married William Forster's daughter.

So, when Henry Edward Kater
Goes to answer his creator,
Will the angel at the wicket
Say, on reading Kater's ticket --
"Enter! for you're no impostor,
Son-in-law of Billy Forster!"
