"I don't think I've ever come home from a tour the same person I left, so there is always a moment where the people you come home to wonder if you're going to get on with them. Or if they even want you in the house."
- Bono, 1990
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.
