Knockturn Alley Lyrics

Went down to Knockturn Alley today
I went into the darkest doorway
I said, "I want something dangerous
I want something useful
And powerful
And I want it by the handful..."
Well, he just looked at me strange
I said, "Don't you know who I am?
Don't you know my father?
Haven't you heard? We're both Death Eaters

Who are you?
You're just a dirty little shopkeeper."

"So give me something that'll really knock
