- Maestro: Go on, then. Do it. Can you find it? The lost chord? Are you enough of a genius?
- The Doctor: Oh, I would never call myself that, Maestro. But I have lived. And I have loved. And I can only smile like this because I have lost so much, I've experienced everything, every single thing, and if that's where music comes from... I can find the chord to banish you.
- Timothy Drake: Henry, get away from him.
- Maestro: Them.
- Timothy Drake: What?
- Maestro: Me.
- Timothy Drake: What?
- Maestro: I'm them.
- Timothy Drake: You're who?
- Maestro: "You're who?"
- Ruby Sunday: I wanna see the Beatles recording their very first album.
- The Doctor: [long pause] Seriously?
- Ruby Sunday: [rapidly] Well, you asked! If we could go anywhere in time and space that's where I'd go because my mum, she had a girlfriend, Claire. And I loved Claire, and she was dead into vinyl. She had all the Beatles' albums, so we'd play 'em every day after school. Ten years old I was. We had Revolver, The White Album. So yeah, if I could go anywhere that's where I'd go.
- The Doctor: That... is... AMAZING!
- Ruby Sunday: Oh, wait, seriously?
- The Doctor: People always say the Titanic, or Mars, or Bethlehem! But the Beatles? Why have I never done that before? Come on!
- The Doctor: Maestro! The Doctor.
- Maestro: That was you in '63, wasn't it, sweetcheeks? You stepped from one time to another, like... the Lord Temporal, who trapped my father and bound him in salt, yes?
- The Doctor: Child of the Toymaker.
- Maestro: C'est moi, mon cher! I should thank you, Doctor. Daddy was so bad to me!
- Paul McCartney: It's like sometimes, late at night, I get this thought... like, it's so far away... but it's a note. A single note. And then a second. And a third and fourth and fifth. And you put them together and it feels like the most holy thing on this Earth. Like a... G. Then an E. Then a G maybe twice. Then C. And if you put words to it, words right from your heart...
- Ruby Sunday: Thing is, without music, dance must be gone. Noone dances any more! I mean, can you dance without music?
- The Doctor: I mean, you can, but do you want to?
- The Doctor: At this moment in time, Ruby Sunday, you are the only music in the world. Let's see what happens if you bring music back.
- Ruby Sunday: Right, I'll just... no pressure.
- The Doctor: I'm sorry... but the power of these creatures is so vast, the whole world could slide into the pit.
- The Doctor: I think without music, the human race goes sour. Without any way of expressing a broken heart, they go to war without even knowing why.
- The Doctor: But there is one thing that I should warn you about, Ruby. And this is really very serious. With all of my adventures throughout time and space, I have to tell you... there is always a twist at the end.
