JOHN LENNON and YOKO ONO

The star dated his former assistant May Pang for 18 months from 1974 to 75, but returned to his wife Ono following the brief relationship.

And Pang insists Ono's methods of helping Lennon to stop smoking were unconventional - she made him drink the cure, which made him physically sick and made him sleep excessively.

She says, "He wasn't ready to go back. It wasn't as clear cut as, 'I'm going to leave you and go home.' He went over there for this method she had to quit smoking. He was going to come back. He said, 'Don't worry, I'll be gone for a couple of hours. I'll be back, we'll go for dinner.' He was gone all weekend. I couldn't get through to him there. Every time I called, Yoko said, 'He's sleeping, he's sleeping.'

"When I saw him on Monday, something wasn't right. Something had gone on. When I asked him, he said, 'I drank this tea Yoko gave me and I threw up.' I could see a whole different person. But I only knew what he was telling me. Did he think he was being drugged? If he did, he wasn't telling me. He wouldn't say much. I let it go. Maybe it's my naivety."
