"My mother's death in a rood traffic accident in November 1978 was in the end, what made my mind up with regard to the band. I am not saying I wouldn't have jumped had she lived but, after her death, there was nowhere else I wanted to be."
- Larry Mullen jr.
According to an interview from 1982 the song 'October' is about the Bolsheviek revolution in Russia in 1917, that brought Communism to power. This theme is mixed with a personal theme, possibly Bono's mothers death.
