I always felt that there was something more between John and George that led to the fight. Probably things building up over the years. I know that according to what I read about John's audio diaries that were never published, it really upset him badly.
I'm partway through browsing the book and has anyone had any interesting surprises yet from reading it and looking through it? Under the school form showing George's registration, under 'additional religous instruction' it was marked No.
