John's work on Yoko Ono albums
I was listening to "Mindtrain" in Yoko Ono's second album and John's guitar work is incredible. He has credit for guitar and multiple instruments on the album but it occurred to me, he would have had great input in these sessions just like in the Beatles, and in all probability given the wealth of his experience, he would have been the de facto studio director, helping to turn Yoko's visions into reality.
When you add the Yoko albums in the 70s that John helped with to his own solo career, you have some impressive productivity.
So between 1970 and 1975 John is an extremely productive musician both in his own solo career and Yoko's, producing great work in both. Not only that, but he is an important anti-war activist. From 1975 he lives a calmer life and appears to devote most of his energies to parenting, until the work on Double Fantasy started in 1980.
None of this fits the picture of him as the unhinged hedonist drug addict.
It doesn't fit the picture of him as a sexist. How many men are there that will put their egos aside so completely and so diligently and quietly help their wives flourish in an independent career?
