I've had some time to think about this. Sorry if this offends but it's just my opinion.
I don't fault Mick for agreeing with Christine. She was a current member of the band and had been for 28 years while all others left. You should support your current bandmates just like an employer should support current employees over former members/employees. Think of it this way Mick is an employer who had a former employee cause a major issue with his company and staff. He supported his current staff in an attack from a former employee. In other words, Bob should have been inducted, but Mick felt it was more important to keep his current band happy than to satisfy a former bandmate from 20+ years earlier. In the end, Bob was right to fight for his royalities and his induction.
Again, sorry if this offends anyone....
