I really don't understand why he would choose to stay poor while he could probably make some pretty good money just by giving some interviews and going to fan conventions.
i suspect not all is well in Jimmys head, and that he may lack the confidence/social skills to present himself to such public scrutiny.
If some fund were set up, where Beatle fans could all contribute, and I was sure he'd get the money, I'd happily put in a few bucks. I think it would be nice for the Beatleworld to rally round what would seem a very worthwhile cause. Maybe we could get Macca to match our contributions (though I doubt it. But it would be a nice PR move for him.)
