The most interesting part of the movie to me is hearing George say that the best band he’s ever heard was that of Ray Charles. Levon Helm was of the same opinion.
@stuartk’s mention of George’s gardening is apt. George talked about not practicing guitar anymore after a certain point (i.e. when he picked up the sitar, from where came my comment about his interest in and focus on that obnoxious-sounding instrument---imo---ruining his guitar playing), and of not being motivated to keep progressing like his pal Eric was (not everyone agrees with that assessment of Clapton). Harrison’s guitar playing in The Beatles is a model of musical taste, of playing for the song. As I said, his solo in "Nowhere Man" is a very favorite of mine. That style of guitar playing unfortunately became passe in the latter half of the 60’s, ironically because of the rise in Rock music of the style in which Clapton himself played: Blues above all else.
But after The Beatles? George was indeed more interesting in gardening than anything else, including music. At least he went out well, The Traveling Wilbury’s being delightful. Actually, in his latter years it was ukulele George was playing, not guitar.
Ya know, Lennon was not shy of expressing his opinion of Harrison’s singing, which was rather brutal. I’d rather listen to George’s post-Beatles singing than Lennon’s, and yes I realize that is a minority opinion. In his defense, at least George didn’t call his wife "mother". Now THAT is pathetic.
