I agree with you in principle that they're rather rare. But there's been a few in that time-span.

The most recent that comes to mind? Read about Bruce Dickinson: https://en.wikipedia.org/wiki/Bruce_Dickinson

Reading that I see musician who did a solo album and some other bands, common, who flys planes... common in actors, and is an entrepeneur.. in beer (food), all super common for someone who has made money.

I don't see a broad range here, this sounds super common, how much crap does Michael Jordan or John Travolta have in common with this guy.

I don't see: patents, masters degrees (not too hard), charities, news articles, really anything that shows he's able to just pick up anything quickly.
