The diva as the undead. Perfect.
I tried to do a little research on this and I think the explanation is as follows. In the Philippines karaoke competitions are popular, and they also celebrate All Saints Day, so maybe this karaoke contest was sometime around All Saints Day. If you are Filipino you might know more and if so can you tell me, am I close?
