Wake Me Up when September Ends

Green Day lead singer Billie Joe Armstrong wrote this song about his father, who died of cancer on September 1, 1982 when Billie was just 10 years old. 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," hence the title.

In the video for this song we see a young couple get separated due to circumstance. This shows the director's view of the song: we should treasure our loved ones and never take them for granted, because they can be taken away from us any moment.
