What an awesome setting for Josh to perform in. He sounded amazing but I still find it extremely odd that he didn't do a Christmas Song especially given he has the most successful Christmas album of all time, plus in his repertoire he also has "O Holy Night" and "Believe" from the movie Polar Express.

It really must have been a magical experience for Josh to look out on the audience and see all those candles.
