This was a HUGE house!  Beautiful.  I guess they sold it when they moved to the Dakota, or did they still keep it?  I assume the mansion was in England somewhere, not in America.

You know, I'll bet Yoko wishes they never moved away, otherwise John might still be alive today.

Look here for all of Johns houses: http://dmbeatles.com/forums/b-lennon/m-1150309051/

It's Tittenhurst Park, which he sold to Ringo in about 1971.

There is soooo much I could say about that.

Wasn't it Yoko's idea to move away? I think if they'd stayed at Tittenhurst, we'd never have seen him. I expect after Imagine, he'd have become a recluse, only occasionally recording. And if someone wanted to kill him, they would have.
