Frey did most of the writing here. Screencaps are from OVA III.

Erin: OVA III is out, which means we finally get to see the Dandy in all his animated action! I can think of no better time to release these lyrics, penned by Frey, to the tune of Sammy Davis Jr.’s song “Candyman”…

Who can take a full deck
Shuffle it with skill
Deal it in style and a razor edge or two?
The Dandy Man
The Dandy Man can
The Dandy Man can,
’cause he shuffles it with skill and makes the cards feel sharp

Who can dodge a bullet
Saunter up a wall
Challenge Alucard and give him more than just a brawl?
The Dandy Man
The Dandy Man can
The Dandy Man can,
’cause he shuffles it with skill and makes the cards feel sharp

The Dandy Man, he’ll
Make every hand he deals
Charming as it is malicious
Talk about vampiric wishes
Who else could make a card game vicious?

Who can help the Nazis
Stake out the hotel
Send in lots of soldiers before coming in himself?
The Dandy Man
The Dandy Man can
The Dandy Man can,
’cause he shuffles it with skill and makes the cards feel sharp

The Dandy Man, he’ll
Make every hand he deals
Charming as it is malicious
Talk about vampiric wishes
Who else could make a card game vicious?

Who can take a bullet
Lose a limb or three
Then dissolve into a deck and come back in one piece?
The Dandy Man
The Dandy Man can
The Dandy Man can,
’cause he shuffles it with skill and makes the cards feel sharp

But the game’s too hard
He can’t deal with Alucard…
