The World's Greatest Criminal Mind is a song written by Henry Mancini.
This slightly different version of the song was meant to be used in place of the movie version of “The World's Greatest Criminal Mind ”. It included more details about the Tower Bridge Job, and also a more introspective look into Ratigan's character, who mentions in one of the deleted verses that his most cruel crimes are caused by what he acknowledges as "dark and devilish urges". The song was most likely cut because of the very dark details given to the Tower Bridge Job, which now appears to have been a mass murder. However, a version was performed by actor Corey Burton for the storybook-read-along CD released along with the film. It is notable that this version is neither cut by Ratigan's forlorn monologue about Basil, or by Bartholomew's word-slip and subsequent demise; these two elements would likely still have been present in the movie, but were cut in the CD's version.
RATIGAN: From the brain that brought you the Big Ben Caper,
The Head that made headlines in every newspaper
By scampering up and tampering with
And hampering times and becoming a muth,
Now comes the real tour de force!
The Big Ben Crime was fine for its time,
But now that I'm back again,
An even grimmer plot has been simmering
In my great criminal brain!
THUGS: Even meaner? You mean it?
Worse than the widows and orphans you drowned?
You're the best of the worst around!
Oh Ratigan! Oh Ratigan! The rest fall behind…
To Ratigan, to Ratigan, the World's Greatest Criminal Mind!
RATIGAN (spoken) : Thank you!
(sung): When these darks and devilish urges guide me,
This cruel and unusual gift that's inside me
Does wondrous things like the Tower Bridge Job,
That cunning display that made Londoners sob…
Picking them off one by one,
Picking them off -- just for fun!
My view from the Bridge,
As all of them bogged and sank!…
But now, this matchless plot has been hatching
Some much more unnatural prank!
THUGS: Even louder, we'll shout it:
No one can doubt what we know you can do,
You're more evil than even you!
Oh Ratigan! Oh Ratigan! You're one of a kind! To Ratigan, to Ratigan, the World's Greatest Criminal Mind!
