In addition to the numerous released songs that the Beatles composed in (or about) India, there are others that were not completed, including these:
1. Child of Nature (became Jealous Guy)
3. Dehra Dun
The Beatles stay in India ended on a sour note and aside from George, did not change them in a permanent way. And yet this opening to India produced a revolution in the West. Cults and Eastern religions in general now got a hearing with younger generations that they had never experienced before.
I remember reading a book on cults when I was a kid that included ISKON and the Moonies, I think it talked about the Beatles influence. I would like to see something in depth on the subject, to trace just how influential the trip to India was on the popular culture.
