We were there the first night of the Candlelight Processional, but were at the 8:15 performance. I thought it was very good. We saw two choir members get taken off the stage (they looked sick). Also, we noticed that some choir members on the left and right of the stage did not know the words to the songs.
One other note, I thought the Interpreter who was signing for the deaf was awesome. At first I thought she was over-the-top, but then it occurred to me that for the deaf people, she is the instruments, the vocals, the lyrics... everything. I liked watching her.
