The biggest moment of Disney's Family Singalong saw the original High School Musical cast reunited to perform the first movie's finale son, "We're All in This Together." Vanessa Hudgens (who played Gabriella), Ashley Tisdale (Sharpay), Lucas Grabeel (Ryan), Corbin Bleu (Chad), and Monique Coleman (Taylor) all joined in for the performance, which was recorded via Zoom as the cast all quarantined. They were joined by members of the Disney+ High School Musical the Musical: The Series cast and other Disney friends.
