Looking at some of the recently-added Sesame Street episode pages compiled thanks to "trusted sources", it seems like quite a few of the episodes chosen for included on iTunes' "Sesame Street Classics" releases had repeated street stories from two years earlier. This was the case with the episode about the broken window, Bob arguing with the phone, and Olivia assisting Placedo Flamingo.
I wonder if they deliberately chose episodes with past street stories to give fans a bit more than just the three seasons included in each volume (well, all the inserts from past seasons would also help).
And now I wonder if any of the episodes that aired on Noggin were repeated stories from past seasons (well, I know that Noggin did air both the season 25 premier and the episode that repeated its plot).
Thinking about it lately, I'd like to see an official document or whatever of an episode that had its street scenes reused. I can't imagine they'd need a proper script for that, since they wouldn't be writing new dialogue (and I assume all sketch/insert scripts are written as separate script pages... though the parts of the first episode script shown in the 40th anniversary book show that the proper first episode script did include dialogue from the first Ernie and Bert insert). Most Sesame Street scripts I've seen show dialogue and stuff written for the street stories and a listing of inserts to appear between those, I guess when episodes were repeated they might have just had a few pages running down the segments. Or maybe they did just copy the previous scripts and put in segment listings.
