MK will make a lot more than John because of the publishing.
But John seems like a sensible guy and I’m sure he invested wisely.
Yes, I'm sure that John doesn't need to anything for living, all that he does is just for having something to do, owning the pub, painting, the exhibitions of their paintings, his records and his live shows, and now his book. And also have fun.

He's just keep himself busy.
