Got to admit as great a song writer as Lennon was I lost a bit of respect for him when he started promoting this no talent, can't sing, poor excuse for a performer wife of his.
"Imagine" (pun intended) as I might I can't see or hear anything in this woman that is entertaining, maybe except on a clown like performance to be laughed at. But in reality even in that respect at best she would be a "sad" clown.
Later,
After reading up on Lennon a bit, I feel that both were well suited to each other, the ordinary everyday stuff was just boring to him and in Ono he found someone who like himself came up with crazy schemes or "happenings" as he liked to call them, one fed of the other I feel.Baggism, bed-in with a big poster saying Hair peace, how crazy can you get, but it sure got the attention of the press.

Lennon also felt that taking drugs such as LSD only served to enhance his creativity, and both him and Ono as you probably know tried herion as well, though didn't inject as they were afraid of needles.
A lot of great singers seem to have a self-destructive trait like this, its hard to understand.
Great songwriter though and a fascinating character to spend a little while reading about.
I often wonder would he have given up his life of being a beatle if he had any inkling of meeting an untimely and sad end.
