When I read the DVD Talk review and saw that one of the bonus clips mentioned was Rainy Day Song, I thought the song title sounded familiar, though I thought it was a song sung by Bob (forgetting that that one is from the early 1970s). Then I looked it up on Muppet Wiki, and seeing the image looked familiar (for some reason I didn't get this sense of familiarity in the past when seeing the image in episode guide pages). But then I clicked on the link at sesamestreet.org, and it all came back to me. I recall seeing this segment as a kid, but hadn't thought about it or remembered it in who-knows-how-long. Sudden instant recall effect. Rewatched it several times, catchy tune, a number of the visuals came back to me just before I saw them in the clip. I am so glad that this particular clip is going to be included.
