From the very first "Aaaahhh, freak out!" the room knew exactly what kind of night it was going to be. The chorus committed to that groove with crisp, unison entrances and tightly stacked harmonies, layering the iconic hook over a foundation that felt as steady as a metronome and as alive as a dance floor at peak hour.

The four featured singers traded leads with easy chemistry. Hession's bright, confident lead set the tone; Nicholas added warmth and lift; Lucas carried the song's higher passages with clean precision; and Cummings, stepping out from the conductor's role, brought a generous, communicative presence that gave the performance an almost benedictory quality. Their interplay on the famous "I got all my sisters with me" tag was joyful and unforced.
