If memory serves correctly, this must be the first upload on the Sesame Street Classics channel that features "Elmo's World", and the first episode from the 21st century to be released to such channel. The 2001 season was the last season before the format change that involved one prolonged street scene and fewer short segments, and of course, "Journey to Ernie" whose Big Bird/Ernie segments were heavily reran to death.
At least, in the 2001 season, there were some classic segments from the 1970s and early 1980s still being used. I was even amazed to see a Canadian-produced cartoon segment, Slot Machine Legs, as recently as 2001.
