I agree with the decision to continue the approach and land after experiencing an engine failure on final. If you're already configured and in a position to land safely, deal with the emergency on the ground.
As a side note, I follow an A-320 "discussion" group on Facebook, and at least two times now, the question about whether to continue or go around on the final with an engine failure has been asked. Most of the responses from pilots of foreign carriers say they would go around no matter what, whereas US pilots overwhelmingly said to land.
On the bus, I’d probably just land. Maybe crank an APU?
