I doubt Guy or John Illsley get "mates rates" at all, why would they? as I have said, it is a commercial business, like other artists, they would have to book time direct with the studio, not just ask Mark. Yes, he owns it, but I doubt he gets involved with the day to day issues, that is why he employs someone to do it. Guy has his own studio too, so he wouldn't need to book much time in BG for his own purpose anyway.
