"I have not spoken to Tom since before ‘California’ came out. So not for a couple of years. But like I said before there’s no bad blood, it’s just we haven’t spoken. I mean he’s dedicated so much of his life to [UFOs] and so much time and energy researching things and listening to people speak, and talking about it himself, that it would seem like a total bummer if he didn’t get a chance to fly into outer space and see for himself."
