This guy has posted a huge list of YouTube links to Sesame Street clips, including some fine celebrity appearances (Robert DeNiro, Norah Jones, Johnny Cash) as well just plain sweet bits that make even Heathen smile or, maybe, feel a little sad.

Do NOT miss the funktastic song by Stevie Wonder in a bit that can’t be from much later than 72 or 73.

Oh, and in a related development, it looks like the commercials Gladwell mentioned that we blogged about a few days ago are also on YouTube, and elsewhere we turned up an MP3 and transcript of the long-lost “Lower Case N” segment.
