To celebrate Ian Leslie's long anticipated biography of John & Paul, here is a look at a vintage McLennon article written by Michael Gerber all the way back in 2015. Don't skip the comments. Gerber responds to them and they bring out even more insight.
From the article: "A love affair between John and Paul, ended abruptly in March 1968 and followed by Paul’s departure from Rishikesh, explains a lot that the conventional narrative doesn’t."
From the comments: "But this is an obsession for a significant subgroup of Beatle fandom, and a significantly thoughtful, well-read and (strange as it may seem given the conjectural nature of the topic) evidence-based subgroup at that. And I’m as interested in that subgroup as I am in the unanswerable question itself."
