I just finished watching. 'John and Yoko: Above Us Only Sky' on Netflix. It was really really good. Shot in 1971, the year the 'Imagine' album from former Beatle John Lennon, was recorded and released. I was moved by the music, but something Yoko said/did, moved me even more.
I'm now convinced that John Lennon had supernatural intelligence, but not only because of the lyrics to his songs. At 5-years-old, John Lennon, not yet a music icon, said something to one of his school teachers that is a testament to this day of his extraordinary wisdom.
