Audio problem: In the club in which Nancy is dancing (and Keung goes to talk to her), there is dance music playing. This is not a score to the film/scene, but rather an actual song being played in the club. Then why is there also a rock band playing guitars/bass/drums, and why can't we hear it? It's also quite obvious that the band isn't playing in harmony with that dance song in any form, either.

In a later shot, he is actually singing. Still later in the scene, he is shown just standing on stage and not singing.
