The "If ... than I'll suck your ...." is actually a common saying from long ago for people his age." I've heard it many times. It's shocking the first time you hear it. For people younger something akin is "That's not going to happen". Ted is a passionate and outspoken person. He's not shy and he doesn't need to be. He's living the life he chooses. He apparently made good investments that did not include kilos of cocaine and heroine like his colleagues of his time. Good for him. I respect any 60's or 70's rocker who is alive today. And I respect anyone's opinion even though it may differ from mine and/ or not be a popular opinion.
Yes, I'd imagine he'd have to be, what with his serial carnal offerings at interviews, concerts and so on.
