Sorry if I am only tell you this little details. These are the only things that I can remember.
There was a music video, a kid (as I remember he was probably a black kid) wanted to enter to a disco. He went there after a lot of difficulties then he danced on the disco like a professional dancer and make everyone shocked!
The only other detail I remember ( I am not sure) was that people (maybe some of them) wore mask in disco!
