How To Get To Sesame Street?

I once said that the '70s was the worst decade for music. I think I might have been judging too harshly, and prematurely, with a lack of knowledge. I've been going back and becoming familiar with funk recently. The '70s, it appears, was more than just disco. And while disco is probably the worst music human kind has ever perpetrated, there's lots of really awesome stuff that took place in '70s music. My example is this video. This was an original composition that Stevie Wonder did for a friggin' appearance on Sesame Street. If crap this awesome can come from an appearance on a kids TV show, then the decade can't be all bad, and might actually be pretty damned awesome. I guess I need to investigate further.
