This video is rough. What starts off as kids playing Weezer's "Undone - The Sweater Song" at what appears to be a talent show just melts down into a humorous fail at the end.
Don't let this setback get you down kids. I'm sure that all musicians had their flubs they aren't proud of. I'm sure one day when you are raking in millions after making that one hit song everyone loves, you'll look back at this video and laugh as much as everyone else has.
