I find it strange that on the one hand his family claim that he wasn't fit to do the concerts, but on the other claim for lost future income on the basis of him performing at concerts etc. They can't have it both ways.
The Golden Goose is dead. Are any of the Jackson family talented to succeed at performing in show business today? Would any of them have risen to prominence without the talent of Michael? I think not. They are still trying to cash in on his name.
