Sesame Street had a numbers song medley with Pantatonix, maybe there should be a letters song medley with some music grouc (maybe even Pentatonix again). Maybe include ABC-DEF-GHI, J Friends, La La La (or The National Association of W Lovers), D Duah Duah (or Disco D), and I in the Sky (and maybe C is for Cookie if they feel they have to...).
Ooh, someone could do an "Evolution of Sesame Street" medley for their 50th, like they did with Michael Jackson and Beyonce.
Seeing this, it would be cool for the 50th anniversary to bring us an "Evolution of Sesame Street" DVD. I often think about ideas for Sesame Street DVDs, especially for the anniversaries, but now I'm thinking for the 50th anniversary, maybe have the selected clips be stuff that are more-or-less period pieces. Stuff that people can tell are from the eras they're from. Not timeless-enough Muppet or animation segments that were repeated for decades, but stuff where characters look a way they wouldn't for long, characters dressed in styles that weren't popular for too long, parodies of things people have forgotten about, appearances by celebrities who were near their fifteenth minute of fame, disco tunes, characters who were only active for a season or two... Though some of those things mentioned were repeated for years after they were dated. Then again, a better title for something like that (better than "Evolution of Sesame Street") would be "Sesame Street Keeping with the Times". And it might be hard to include current stuff as you never know what will be dated in a few years.
It would be cool if there was an official "Evolution of..." release for a single song that's been remade/reperformed many times. Like "Evolution of Rubber Duckie", "Evolution of Sing", "Evolution of The People in Your Neighborhood", etc. (and maybe "evolution" is the wrong word here). It'd make a cool audio release (though it might work better as a digital release), or a video release (though maybe a Warner Archive release would be better for this), or a special bonus feature on a DVD (could be a good trend for bonuses on DVDs released during the 50th anniversary year), or maybe just make it one of those clip "collections" that Sesame Workshop puts on its YouTube channel. An "Evolution of..." thing for the characters would also be cool.
