"There were two things going on, memory and loss, a portrait of a girl in a shimmering lemon dress that kept it sexy and playful and the pathos of a man separated from the things he loves. Lemon is about leaving home, versus not leaving home."
- Bono on Lemon
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.
