Continuity mistake: At the end of the performance of she's so gone Stella and Olivia suddenly switch sides of the stage.
Continuity mistake: During the opening song, as Gary is dancing with the crowd, right before the chorus of the song kicks in, Gary spins around, with his hand to his nose like he's about to sneeze. During the first shot from the front, he puts his hand up to his nose, and begins to turn in a clockwise direction. He turns about 15° as the camera cuts to the next shot, and he has suddenly turned a complete 180° instantly between shots, and is facing the opposite direction.
