I came across this a few days ago but didn't have a chance to watch it until just now. It is awesome! Kermit is so...so totally far out, man. C... had some vintage Sesame Street up a few weeks ago, and this is so vintage it predates my experience. Until now!
If you liked that there are a few other videos up here with the same theme. Those "Old School" Sesame Street DVDs may just be must haves for this household of Muppet enthusiasts.
p.s. My little "history of" series will continue soon.
