I would like to guess H.
Let’s have a good old “Q”.
And a U. G&S, represent!
FHQU – sounds obscene, or certainly vulgar at least!
“I know the kings of England and I quote the fights historical, from Marathon to Waterloo, in order categorical.”
G&S indeed, of course. All yours, EH!
Thanks!

I would like to guess A, please.
I, please.
T, please
Sorry - brainfart! This is the phrase I meant to do, with the already-guessed letters now put in:
T A ___ ___ / ___ ___ ___ / A ___ ___ / ___ ___ ___ ___ / T ___ ___ / ___ I T ___ /___ ___ ___ ___ / ___ ___ ___ I T .
I knew there were A’s in the sentence just by looking at it.
Now I would like to guess H. 
E for me, please.
Right you are.
T A ___ E / ___ ___ ___ / A ___ ___ / ___ ___ ___ E / T H E / ___ I T E /___ ___ ___ ___ / ___ ___ ___ I T .
How about “K”?
Yup.
T A K E / ___ ___ ___ / A ___ ___ / ___ ___ K E / T H E / ___ I T E /___ ___ ___ ___ / ___ ___ ___ I T .
How about N, please.
Might as well guess an “O”.
Righto.
T A K E / O ___ ___ / A N ___ / N ___ K E / T H E / ___ I T E /___ ___ O ___ / O ___ ___ I T .
Let me guess the obvious: D.

T A K E / O ___ ___ / A N D / N ___ K E / T H E / ___ I T E /___ ___ O ___ / O ___ ___ I T .
Then, there should be a “B”.
