“I heard the phrases and I wanted all of me to call out in a song, a song that doesn't have words, a song that almost doesn't have noise. A lot of people take a short cut and call that feeling of song love. They just call it that because there isn't a way to describe it. But the word love doesn't describe the half of it. It doesn't do anything to bring to mind the song we all want so desperately to sing.”

“Sometimes, the Lord just takes blessed people because they've filled their purpose early. Everyone plays their own song. They sing their story to the world and leave behind a melody of memories. Sometimes... their song is cut short and ends too early. But that doesn't mean their music was any less sweet or that they left any less of an impression.”

“In the distance I hear a song - a simple song - a song of despair - a song of longing and a song of sorrow.I have forgotten the words and the rhythm, but I sing.Yes, I sing.”

“When we were doing interviews for our bio, I described hearing that song for the first time to be like Sara was standing on my chest. I just felt really sad, and that was having heard all the other songs in order leading up to that one. I know that when Sara was writing these songs it was during the end of her relationship and it was someone she’d been friends with for almost ten years and been with for four years. It was just the psyche of it, when you’ve known someone for half your life, literally, and then have to leave them, and not necessarily because you want to but just because it’s the right thing to do, and it’s just not healthy and you’re not good anymore, there’s no growth and you have to have growth. And when I hear that song, the idea of that all happening just makes me sick to my stomach a little bit. But it’s in an enjoyable way.”

“River Song: Use the stabilisers! The Doctor: It doesn't have stabilisers! River Song: The blue switches! The Doctor: The blue ones don't do anything, they're just... blue! River Song: Yes they're blue: they're the blue stabilisers! [presses the button and the TARDIS indeed stabilises] See? The Doctor: Yeah? Well, it's boring now, isn't it? They're boring-ers! They're blue... boring-ers! Amy: Doctor, how come she can fly the TARDIS? The Doctor: You call that flying the TARDIS? [scoffs] Ha! River Song: Okay, I've mapped the probability vectors, done a foldback on the temporal isometry, charted the ship to its destination and... [presses a button, the cloister bell clangs] parked us right alongside. The Doctor: Parked us? But we haven't landed! River Song: Of course we've landed; I just landed her. The Doctor: But it didn't make the noise. River Song: What noise? The Doctor: You know, the... [does an impression of the TARDIS materialisation sound] River Song: It's not supposed to make that noise. You leave the brakes on.The Doctor: Yes, well, it's a brilliant noise. I love that noise.”

“I've played the song for a lot of people who respond, 'Hmmmm, this is interesting,' but in a way it's more like 'There are two exits in this room, the window and the door. If this song doesn't end soon, I'm going to opt for the window.”
