Question about The First Day of School

Hi... My question concerns the version of this classic as performed by the Dead Hensons which airs frequently on MCR (Muppet Central Radio). At the end of the song—much like in the original—the singer states how there are more children out there than the ten who get counted throughout the course of the song. What I'd like to know is, what are all the names of extra children that get mentioned?
I hear "David, Zack, and Joe... Coby? and Kolchat?", but can't discern the rest.

Hope to get some replies soon and thanks as always.
