Others have answered, but I am surprised that they hadn't uploaded it sooner. Of course I'm also surprised it hasn't been released on home video by now (usually if they release an example of Grover doing near and far it's always the "Over, Under, Around, and Through" song). And I checked on Muppet Wiki some time ago and saw that the classic season 6 "near and far" hasn't been on the show since the late-1980s (I can see why it might not have been on the show since around 2001, but the late-'80s???).
Every once in a while they upload clips that I thought had already been uploaded years ago (the only example I can really think of right now being The American Revolution: National Bird). Of course now they're uploading classic clips converted into high definition, so I wonder if they would (or maybe have and I haven't noticed yet) re-upload certain classics if they're in HD.
