We're all in this together!
Zac Efron made a special appearance during TheDisney Family Singalong to introduce his former High School Musical co-stars -- Vanessa Hudgens, Ashley Tisdale, Corbin Bleu, Monique Coleman and Lucas Grabeel -- as they reunited to sing "We're All in This Together."
"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," Efron began. "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."
Kenny Ortega, as well as the cast -- minus Efron -- then reminisced about their time on set and the song, before kicking off the epic performance.
"When we recorded 'We're All in This Together' all those years ago, did you think that it could become the anthem that it is today?" Coleman asked.
"It's popping up everywhere. It's crazy," Bleu replied. "It just goes to show you, though, there is nothing like the power of music to lift up the spirits."
