it seems that all the anthem arrangements were by one guy...I read an interview with him. He got 'mostly' favorable responses to his arrangements, but you can't please everyone. A few had to be shortened to fit into the 60sec. limit, which upset a few..(Thailand's is almost 5 minutes long)

I thought the USAs was not too bad, but the violins on "rockets red glare" section was almost inaudible.
