In the movie Before A Sunset there was a song playing at a party before the main character crawled into the vent, what was it?
look in the credits?
With that info, the best I can do is point you in the direction of the soundtrack.
Sorry, it was after the sunset. I’ll just google it.
If you still have the movie, you can turn on the closed captioning and watch that scene. It will usually say something like “party like its 1999 by prince playing”
Really? I’ll give it a try. Thanks.
