THE BEATLES' sound engineer GEOFF EMERICK still chuckles when he recalls the sight of Yoko Ono bedridden at Abbey Road studios - because she wore her sexiest bedroom attire in front of the Fab Four. JOHN LENNON set up a bed for his girlfriend in the studio while he was recording ABBEY ROAD after Ono was injured in a car accident. Many fans still believe the act was the beginning of the end for the group - but Emerick insists it was just hilarious. He laughs, "She became part of the furniture. She could've been hanging from the ceiling in the bed; we just took it in stride. "It was a big Harrods bed with white painted brass headboards. She was in bed in the studio in her negligee, wearing a black band to hide the scar from the accident. "We saw the funny side of it but, by then, nothing surprised us."
