A Lovely Night is a song sang by Mia (Emma Stone) and Sebastian (Ryan Gosling) after they meet for the second time, and are trying to find their cars. It is part of the La La Land: The Complete Musical Experience and the La La Land (Original Motion Picture Soundtrack).
Seb: The sun is nearly gone...the lights are turning on. A silver shine that stretches to the sea. We've stumbled on a view that's tailor made for two....what a shame those two are you and me. Some other girl and guy would love this swirling sky. But there's only you and I, and we've got no shot. This could never be. You're not the type for me.
Seb: And there's not a spark in sight. What a...waste of a lovely night!
Mia: (Clears throat) You say there's nothing here? Well, let's make something clear. I think I'll be the one to make that call!
Seb: But you'll call?
Mia: And though you look so cute, in your polyester suit, you're right, I'd never fall for you at all! And maybe this appeals to someone not in heals, or to any girl who feels, there's no chance for romance. But I'm frankly feeling nothing.
Seb: Is that so?
Mia: Or it could be less then nothing
Seb: Good to know! So you agree?
Mia: That's right.
Seb and Mia together: What a waste of a lovely night!
