I was torn on his RENT performance. I thought he was really off key on the first number, but eased into it eventually. It wasn't the best Mark I've ever seen, but he wasn't terrible. I'll be very curious to see what he's like as Seymour. I just have a hard time seeing it.
I think he will be great as Seymour. He'll certainly feel comfortable in the glasses.
He was a wonderful Mark (at least at the perf. that I saw). He had a very laid back and warm stage presence. He sang the songs very well, and did a good job on the acting. It was a very smooth performance, all the way through.
If you go to the LSOH website (http://littleshopofhorrors.com/emailpop.htmlhttp://littleshopofhorrors.com/emailpop.html>http://littleshopofhorrors.com/emailpop.html), there's a pic of Fat One dressed as Seymour. God help him- he looks terrible.
