Pete Best. Really, to go through life knowing you could have been a household name for one of the most iconic bands that ever existed, and be rolling in cash, must really suck. I can only imagine the demons associated with that. Or Dave Mustaine. While he formed one of the most iconic metal bands, he could never get to the level of fame his former band Metallica got. No matter what he will never be as well known as them, or have nearly as much money, or (any) mainstream awards. His bitterness is so evident in every interview he does. Shit must suck.
Seriously, comparing Dave Mustaine to Pete Best? Mustaine has a shitload of money and he's really famous. No comparison really, and definitely no reason to feel bad for him!
People prefer the Mustaine stuff, anyways I did. I think people like the 5th beatle or the guy who quit pirates of the Caribbean
