After John and his wife returned from India, Cynthia Lennon was urged by John to go on holiday. She traveled to Greece with Magic Alex and Jenny Boyd, older sister of George's wife Patti. Shortly thereafter, John invited Yoko to his house at Kenwood. It was during this visit that John and Yoko went to the attic studio, dropped acid, and recorded electronic shrieks and noises eventually released as the album Two Virgins. Cynthia returned from her trip to find John and Yoko sitting in bathrobes on the floor of the Sunroom. Cynthia filed for divorce on August 22, 1968, upon learning that Ono was pregnant by John.
Yoko began attending Beatles' recording sessions during The White Album. She became a constant companion to John and can be seen sitting by his side for most of the Let It Be sessions. To the other Beatles, this was highly unorthodox since Beatle sessions were always closed except to guest performers Eric Clapton ("While My Guitar Gently Weeps") and Billy Preston ("Get Back"). Later, in June of 1969, John had a bed brought into Abbey Road Studios so that while the group recorded, Yoko could recuperate from injuries sustained in a car accident in Scotland.
