I'm starting this thread out of fairness, so everyone can comment on this decision. We're coming close to the end of season 44, and while Matt Vogel has performed the Count for one Sesame segment (so far), he's also performed him in practically every other appearance elsewhere (Katie, Fallon, Cumberbatch, etc.) I think at this point we can add Vogel to the Count's performer box, yes?
Four yays are good enough for me ;) I'll go ahead and add. The Casting History probably isn't needed now anyway. The performer note can be moved to the Notes section, or a "Performing the Count" section could be created similar to what's on the Big Bird or Piggy pages.
