8:54 p.m.:Zac Efron has arrived...to introduce his former costars. He's got "patchy wifi," Ryan Seacrest says, and we believe it. He's very blurry.

"Hi, everyone. I hope that you're safe and that you're healthy and that you're doing as well as possible during these unprecedented times," he said. "It's my greatest pleasure to introduce a musical performance by some of my oldest friends and some new ones. I hope that you enjoy, and remember, we are all in this together."

Thanks, Zac Efron.

8:56 p.m.: The rest of the High School Musical cast, as well as the Zombies, Descendants, HSMTMTS casts and even Tik Tok star Charli D'Amelio all look very clear and not "patchy" at all as they not only sing but also dance to "We're All In This Together," a sort of anthem for these troubled times. Lucas Grabeel even has a fedora!

9:00 p.m.: The night gets closed out with Michael Buble and Demi Lovato, though they're not performing together. Buble performs, and then Lovato performs, and it's all while small children hold up signs thanking essential workers.
