Green Day lead singer Billie Joe Armstrong wrote this song about his father, who died of cancer on September 1st, 1982. At his father's funeral, Billie cried, ran home and locked himself in his room. When his mother got home and knocked on the door to Billie's room, Billie simply said, "Wake me up when September ends,"

I'm so sorry... ♥
