Voldemort: How does a greasy-haired, hook-nosed son of a witch and a Muggle
Dropped in the middle of a forgotten puddle in Cokeworth by providence, impoverished in squalor
Grow up to be a hero and a scholar?
Harry: The namesake of Albus Severus Potter
Got a lot farther by working a lot harder
By being a lot smarter
By being a self-starter
By being a genius Defense Against the Dark Art-er
Dumbledore: And every day while Muggles were being slaughtered here and away
By Death Eaters, he struggled and kept his guard up
Inside, he was longing for something to be a part of
The brother was ready to beg, steal, borrow or barter
Lupin: Then the prophecy came, and devastation reigned
Our man saw his future drip, dripping down the drain
Put a wand to his temple, connected it to his brain
Cast a Patronus from his pain, a testament to his shame
Lucius: Well, Dumbledore found out, found him insanely ravin'
Tried to tame him and made him a double agent
Helped him find redemption, release himself from blame
Said, "All of Hogwarts' gonna know your name" - What's your name, man?
Snape: Professor Severus Snape
I'm the Potions master, Mr. Snape
And I regret that I've turned out this way
But just you wait, just you wait
Lily: In '92 Quirrell split, from Voldemort, who's head-ridden
Three years later, Voldemort returns from the dead, riddle
Me this, stronger than ever, horcruxes six
Company: And soon Snape found out that Dumbledore had gotten sick.
Bellatrix: Took an Unbreakable Vow, to protect the Malfoy boy
Pretty soon Malfoy finds out dark magic's not a toy
And Snape's saying
Bellatrix & Company: "Hold on, I'll do this myself"
Bellatrix: And with one killing curse he knocked Dumbledore right off the shelf
Harry: There would've been nothing left to do
For someone less astute
He would've been dead or destitute
Without a hope of restitution
Kept on spying, lying right to the Dark Lord
Taking more risks that he couldn't afford
Meanwhile, reading any potions book he can get his hands on
He's plotting for the future, see him now as he stands in
The headmaster's office, with Dumbledore feeding him plans
At Hogwarts he's become a new man
Company/Snape: At Hogwarts he's become a new man/Just you wait (x2)
Company: At Hogwarts he's become a new man
Women: At Hogwarts
Men: Hogwarts
Snape: Just you wait!
Company: Severus the half-blood prince
We are waiting in the wings for you
You could never back down
You never learned to lose a grudge
Oh, Severus the half-blood prince
When the wizarding world sings for you
Will they know what you overcame?
Will they know how you changed the game?
Hogwarts will never be the same, oh
Voldemort: His portrait's in the office now
See if you can spot him
Another half-blood Slytherin
Who came up from the bottom
The second war destroyed his rep
And Potter near forgot him
James, Sirius & Bellatrix: Me? I fought with him
Harry: Me? I died for him
Dumbledore & Narcissa: Me? I trusted him
Lily: Me? I loved him
Voldemort: And me? I'm the damn fool that slaughtered him.
Company: There's a million things I haven't done, but just you wait
Voldemort: What's your name, man?
Company: Severus the half-blood prince!
