Sesame Street is taking us back, way back to when Kermit the Frog was a regular and Oscar was a complete grouch. “Sesame Street – Old School, Vol. 1 (1969-1974)” and “Sesame Street – Old School, Vol. 2(1974-1979)” are now a DVD. You will see cameos from the past featuring popular entertainers of the day. There will episodes of the Sesame Street friends riding the subway. Some of those that watched the original Sesame Street shows may actually have young grandchildren of their own. These DVDs are more for adults to look back and remember moments from the past.
