Just needed a reminder. Didn't really pay attention much to the show around then so I kind of forgot. But at the same time I seem to remember them having episodes where Mr. Hanford was kinda grooming either Savion or Gina to take over for him. Seems that Hoopers always had an assistant that would take over for the store for a while when they didn't use those actors in certain episodes.
Still, while whatever conspiracy about Bob and Gordon can be had, Sesame Street had a bigger cast member turn around rate than we realize, and often times it was because the younger actors moved on to bigger things. How long was Raoul Julia on? Went on to have a film career. Charlotte Rae. Sitcom star, got popular enough to get a spinoff sitcom as well. Savion created Stomp, a big hit in the 90's and still dancing.
