It's the Disney centenary movie, which movie afforded Disney creatives the opportunity to slip in all sorts of unflattering meta references regarding the company's corporate imperatives, hypocrisy around its attitudes to the LGBTQ+ community, and the all-consuming obsession with the bottom line of CEO Bob Iger.
Get ready for queer-affirming anthems and songs about starting a union. Be prepared for a Disney villain whose power comes from crushing Disney dreams. Also there's a song with dancing chickens. It's gonna be a wild ride.
NB. The original video was copyright claimed by Disney because Disney doesn't understand nor does it care about fair use, and so the only way to get round the claim without cutting 18 minutes of video was to do some frankly stupid transformative editing. The fact that this is allowed despite the content and purpose of the video being EXACTLY THE SAME should clue you in to how broken YouTube's Content ID system is. Anyway, if you want to see the original without the weird TV filter and about 20 seconds of extra content, you can see it on my Patreon at the following link:
