Stephen' spoint seems valid, but the humongous difference is that MK and Guy lived that fame, it feels natural to them. They have fulfilled the desire, if they ever had it. It no longer bothers them, it is a part of their life.
As for Rob, I find it that being truthful (no question about it) is harsh. And we are not talking here about human lives, we are supposed to be talking about music, art. When you downgrade it to an artful product and then have expectations on another person's lives, I think the balance between the two is lost and with it the real weight of the whole matter.
Simply put, why it means so much to all these people, the Hall of fame. Would they enjoy the music less if they fail, or if they don't show up? I say, a Hall of fame member, might charge 200 $ more, for the next concerts. Does this make any sense? No. They are completely different things. Why mix them up all together?
And if you don't like the last albums as much, (we all like DS more, I believe) well why connect this with the Hall of fame?
My sincere thoughts, no disrespect.
