From an Associated Press interview with Yoko Ono (widow of Beatle John Lennon):
AP: One hundred years from now, what do you want people to know about John Lennon?
Ono: First of all, I'm not sure if I'm not going to be there. Things are changing in this world so much and it might be like we're all going to live as long as we want to. And also John might come back. We don't know anything. So I'm not going to answer that question.
