When Kelly gets a job at The Max, she falls in love with her boss Jeff, and they kiss one night while closing up. At this time she is going out with Zack and it happens a few days before the costume ball. At the ball Zack's band sings, but Zack and Kelly leave to talk after Kelly calls him Jeff. The band mates wait for a few mintues for Zack to come back, then they decide to play with out him. A.C. gets up to sing and then some guy just pops up for off camera and sits down at the drum set (where A.C. is supposed to be). This guy just starts playing. Like, come on, if some guy just came up to my band and started playing I would be kinda freaked. And another thing, he didn't practice with the band and he had NO music, how could he know how to play? And I would like to comment on Lisa and her guitar playing. Just look at her hands, they go in the same path over the guitar all the time, and she doesn't even touch the strings. One more thing, all their voices (while singing) pretty much sound the same.
