Heh, I only just noticed that these three are named after rock stars...

Ozzy - Ozzy Osbourne.
Flea - Micheal Balzary(Flea), Red Hot Chili Peppers.
Slash - Slash, from guns 'n' Roses.

Heh, i'm stupid. I was thinking about Ozzy Being named after Ozzy Osbourne, but I gues Flea and Slash must have somehow crossed my mind. 'twas only when I was playing the game and Listening to one of my Red Hot Chili Peppers albums that I noticed...
