Bill's Dr. Teeth just IS Dr. Teeth at this point. I sometimes have a hard time differentiating Rowlf, Dr. Teeth and Bobo (in the "Life's a Happy Song Finale", I really do hear Rowlf saying "When there's someone by your side to sing," but in the movie it's Bobo). Here, though, he's just in fine form.
The thing about Matt's Floyd right now is that he sounds a lot younger than Jerry. But he's got, for me, the most basic elements of Floyd down - the walk, and the laugh. Loving it.
I've got to hear David's Janice talk more, though... really not sure how I felt about her here. It's good, though, that it's not just feeling like an imitation of what Richard was doing. I think the spirit of the character is still there, and that's what's most important.
