I don't think it was to inspire jealousy, Wingsman!
The other Beatles thought he was mad, and told him so. They said he was pricing himself right out of the market.
I think George was perversely doing his own thing. He didn't have great expectations for the album, because several of the songs had a religious content that he suspected might go over like a lead balloon. But this was his
album, finally, and he was going to do what he pleased.
The only explanation I'd ever heard for the jams is that he expected these spontaneous warm-ups that were so much fun for him would disappear forever, and he wanted to include them. Someone once likened them to bonus tracks on a CD, and I think that's a good analogy. Since he expected only diehard friends would buy the album, it was something he suspected might be interesting to them. No one in their wildest dreams thought the album would be as successful as it turned out to be, critically and commercially. I think that's a lovely payback for any artist who has the chance to follow his heart.
