John Lennon invited Yoko Ono to his house, while Cynthia was away on a vacation with friends, one weekend in May. The two spent a night together in Lennon's attic studio, listening to his avant-garde recordings and finally making one of their own. Lennon discovered Ono was "as barmy (crazy) as I was", and that they connected personally in a way he and Cynthia never had. They finished the recording, and had intercourse as the sun rose that morning. They woke up late the next day, in love with each other, and decided to stay together from then on, even though they were both married to other people. Lennon's wife Cynthia and Ono's husband Anthony Cox both took the news very hard, with their children (Lennon's son Julian by Cynthia, and Ono's daughter Kyoko by Cox) caught in the middle.
