I know there was at least one thread about him, but I couldn't find it.
Anyhow, I saw the show yesterday and this was the first time I saw Sebastian. I have to say I was very impressed with his acting and loved how he put his own spin on the character. His signing is different from Daniel's, of course, but it's very good and fresh! I was sitting in front of two people from Los Angeles who came to see him, specifically, in his new role. They were enthusiastic and so much fun. I love it when the audience around you gets into it as much as you do! :)
