Watch on Soap2day. A concert to benefit the family of Mykel and Carli Allan, the founders of the Weezer Fan Club who, along with their younger sister Trysta, passed away in a car accident in July of that year. This was Weezer's final performance for three years (Goat Punishment shows don't count), and the last to feature bassist Matt Sharp before his departure from the band. Before the encore, the Mykel and Carli's father, Wayne Allan, delivered a speech.
