If for some strange reason you haven't seen this movie yet, in this scene, Don's look-alike performs for a group of the Don's confederates and their girlfriends in an intensely crimson room. (One knows there shall be blood soon, I guess.)
Note: I first thought that the soundtrack of Don was a little forgettable. That was, until I woke up a couple of mornings with "Main Hoon Don" running through my head. And yes, there's a tiger mask in this scene. Why? I don't know. But it is RAD/FAB and catchy--so I am now stamping it with my approval.
