Weird Al Yankovic is an entertainer from Los Angeles. I first heard him quite a few years ago performing live with his accordion on the Doctor Demento radio show. He did a lot of remakes of Michael Jackson songs, some of my favorites include Beat It
Al's version is Eat It
And I'm Bad
becomes I'm Fat
He didn't just pick on Mike, he did some original stuff, and followed other bands, such as Nirvana
What brought Al to mind was his most recent undertaking, a Lady Gaga tribute
Not sure, but for some of them I like Al's version better.
