I have to disagree with you again, Chris. Yoko was most certainly living with Sam Havadtoy very soon after John's death. That is a fact. There are photos to prove it on her birthday on Feb 18. 1981. there was a charming photo of her and Sam alone taken. One of the very rare photos of them. Yoko would not allow photos of her and Sam because she wants to perpetrate the myth of John and Yoko the Love and Peace couple. Sam was already on the scene when John was still alive.
I personally see nothing wrong with her moving on, but why keep it a secret? More of her manipulative crap, which is why I don't liked her. Why was she so phony about Sam? From all accounts, he was a good man and very helpful with Sean when he was little. They are no longer together, having broken up in the Spring of this year.
