Yea, definitely saw a lot of people signing today. The most unique thing I saw was that they had an interpreter for Billy Hill and the Hill Billies. Real fun, the lead guy was actually cracking jokes at her too.
It's actually really cool watching them interpret the shows. I saw the Jedi Training Academy last year with one of the interpreters. Each time she "switched" characters, her entire demeanor changed for the translation. It was really really interesting to see.
