He mighta hated life on the road, y'know with all the bad food, marginal  living accomodations, constant partying, late nights, and beautiful naked girls throwing themselves at him in exchange for an autograph, or maybe a free T shirt.   Maybe it bored him, so he decided to settle down with a nice, very RICH girl (who mighta been one of the naked groupies anyways), and study something pretty useless and even MORE BORING...an MBA (I mean really..the life of a wandering minstrel in exchange for an MBA...Oh M'God it's sickening). 

But y'know Peter...that musician thing never dies.  I predict within 6 months, maybe a year tops, he will shed that shirt and tie (but not the RICH GIRL, if he has any brains), forget about being one of a million unemployed MBA's, and get back in the studio for another effort.  And after that...he'll be smokin' a fat one in the tour bus (oh yeah, Air Conditioned luxury tour bus, courtesy of his RICH INLAWS), and sipping a bottle of Jack Black.
