When I went (evening show) Christine came out and she was very gracious.
Erin, Matt, and Bob came out as well, but the way Matt and Bob signed was odd, they started at the front, then sort of skipped the middle, and went to the end. But they were all very nice.
MLW, John, and Michael Potts didn't come out, and the two little girls came out but didn't sign.
And the show was fabulous too!
I am a firm believer in serendipity- all the random pieces coming together in one wonderful moment, when suddenly you see what their purpose was all along.
