Here's the original American version:

ARE YOU THERE MORIARITY!
Words, Ed. Harrigan; music, Dave Braham. ©1876.

1. I'm located at headquarters, a "Special Officer!"
Cornelius 'Riarity, here, at your service, Sir!
I know the thieves and blackguards too, wherever they may be,
And if you want a "fly Copper," call Moriarity!

CHORUS: I'm a dandy Copper in the Broadway Squad,
A "Metropolitan M. P."
And the young girls cry when I'm passing by,
"Are you there, Moriarity?"

2. The shop-girls going to labor in the morn at eight o'clock,
They wink and blink their loving eyes at me on ev'ry side!
They say I am their darling; with me they'd tra, la, la, le!
Is a smiling way, you'd hear them say,* "Sweet Moriarity!"

* Spoken: "You Duckey!"

3. My uniform is Navy blue, and it fits me like a duck.
I escort the ladies in the street, all thro' the mud and muck!
For Coach and horse stop when I cross; I'm the ladies' own baby!
As on they go, they whisper low, "Are you there, Moriarity?"
