Well, I can see why that happened. The TV station wanted a snippet to air when advertising the show, and what better than to have the Eagles say "Hello" in Chinese and then declare who they were? And the "face the left" bit was borne of necessity so all the photographers could get shots of the Eagles' faces - how could that have been done differently?
The questions were what I found excruciating. Some of them were so insipid!
As for Troub's question.... well.... lol
