(knocks) People?
Do you wanna join my army?
I call it the DA
The Dark Lord has returned once more
Stronger than before
Must make him go away
We used to learn defense spells
And now we don't
What Umbridge says is a lie
Do you wanna join my army?
No, I can't give you extra credit
(Shut up, Harry!) Okay, bye.
HPB
Do you wanna play some Quidditch?
I'm captain now, I make the calls
I think diversions are long overdue
Guess who else thinks so too?
The pictures on the walls
(Hang in there, Fat Lady)
It gets a little stressful, as the Chosen One
So come out and play a game
(Chaser, Beater, Keeper, Seeker)

Please, I know you need me
I'm sure you're wondering where I've been
They say "just kill him", and I'm trying to
But I need help from you
Just let me in
We only have each other
To defend the school
What are we gonna do?
Will you help me find a horcrux?
