I'm looking for a song. It's old, I only remember the video clip. It happens at night, a fatter person appears on stage, a guy who looks like a nerd. He starts singing and people in the room slowly start having fun. the song is sad, it's probably something like electronic pop? I seem to have seen the clip on MTV a lot. I remember everything was in some sort of green filter. I don't remember a single word or melody.
