Had Prince only been a funky, sexcrazed midget, instead of a funky, sexcrazed, musical genius midget, I'm pretty sure he could have been a world class jockey.
Sting looks like a regional hurdling champion to me, and Phil Collins, of course, was probably a big hope in luge og bobsleigh.
And also, I wouldn't be surprised if it turned out a hockey puck knocked out at least one of Shane MacGowan's teeth.
Any other world class athletes among the acclaimed artists?
Prince actually is known to be a decent basketball player. I've actually played hoops with some of his crew at Paisley Park! There's an artice at Sportsline about it!
Going the other direction, Jack McDowell, who pitched for the White Sox and a few other (baseball) teams--he won the AL Cy Young award in '93 as the league's best pitcher--is in a band called Stickfigure. Their website claims that they sound like Tom Petty, Elvis Costello, and the Replacements. Don't know if they're any good.
