This is really a filklet -- not that many words need to be changed to show us the lighter side of Azkaban.

Dementors threw a party in the wizards' jail.
The Death Eaters were there and they began to wail.
The band was jumpin’ and the joint began to swing.
You should’ve heard those knocked out jailbirds sing.
Let’s rock, everybody, let’s rock.
Everybody in the whole cell block
Was dancin’ to the jailhouse rock.

Augie Rookwood played the tenor saxophone,
Dolohov was blowin’ on the slide trombone.
The drummer boy who knew Malfoy went crash, boom, bang,
The whole rhythm section was the Dark Lord's gang.
Let’s rock, everybody, let’s rock.
Everybody in the whole cell block
Was dancin’ to the jailhouse rock.

Bellatrix Lestrange said to Sirius B.
"you’re the cutest jailbird I ever did see.
I sure would be delighted with your company,
Cousin, do the Azkaban rock with me."
Let’s rock, everybody, let’s rock.
Everybody in the whole cell block
Was dancin’ to the jailhouse rock.

Rubeus was a sittin’ on a block of stone
Way over in the corner weepin’ all alone.
Dementor said, "hey, Hagrid, you got a bum rap.
But you're never gonna get out of this death trap."
Let’s rock, everybody, let’s rock.
Everybody in the whole cell block
Was dancin’ to the jailhouse rock.

Travers said to Mulciber, "for heaven’s sake,
No one’s lookin’, now’s our chance to make a break."
Mulciber turned around and said, "nix nix,
I wanna stick around a while and get my kicks."
Let’s rock, everybody, let’s rock.
Everybody in the whole cell block
Was dancin’ to the jailhouse rock.
