I think he died last year actually...due to some kind of intestinal blockage. Kind of scary actually because that could happen to anyone, healthy or not
Anyway, I think Staying Alive will forever be the comedy anthem in movies and TV when some nerdy guy does something studly (i.e.- When a geek gets laid, then the next morning you see him struting out of his house and Staying Alive is playing during the scene.) I think they're actually pretty talented. Didn't they make that song "Funk 49"? That had some great guitar riffs in it
