Watch the 'High School Musical' Cast Reunion from the Disney Family Singalong!

Zac Efron joined the High School Musical cast on the Disney Family Singalong on Thursday night (April 16), though he sadly didn’t sing with them.

The cast reunited to perform the smash hit song “We’re All in This Together” from their own homes. Zac is supposedly quarantined in the “middle of nowhere” with poor WiFi, but he sent in a grainy video that served as an introduction to the performance.

Director Kenny Ortega brought together Vanessa Hudgens, Ashley Tisdale, Lucas Grabeel, Monique Coleman, and Corbin Bleu, as well as the casts of Descendants, Zombies, High School Musical: The Musical: The Series and more, for a great performance.

“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. 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’re all in this together,” Zac said. He unfortunately didn’t sing with the cast, but you can watch the performance below!
