If I'm Mike Love, and I and the rest of my BB bandmates are staring mortality in the face, I don't know that I could forgive myself if the the last Beach Boys gig isn't played by The Beach Boys. And with every additional gig that he books with his current backing band, instead of finding a way to co-exist with Brian, Al and David, the potential for that happening comes closer and closer to reality. They all need to make some compromises, but as long as Mike keeps control of the name, it ultimately falls on him, for better and worse.
To be perfectly honest, I think that if I'd be Mike Love, I'd be just fine touring with my regular "hired hands". Mike's already achieved everything any musician could dream of, and much more. In fact, he already did 45 years ago. So now he's 73 years old, still doing what he loves most, and for the majority of the past 16 years it's been pretty smooth sailing because he's in charge and everyone he works with is basically his employee. Yes, he could take Al or Brian on board, but we've all seen how that works out. Sure, you'll sell some extra tickets, but it turns into one big soap opera every time and somehow everyone ends up with a bitter taste in their mouth. I could understand it if Mike just doesn't want to deal with that anymore.
