You have two young daughters. Did you have any misgivings about being an older dad?

Yeah. I know there’s a finite amount of time I have left to be with them. But because of the nature of what I do, I may get to spend more time with my children than most people do. I spent most of my life traveling like Willy Loman. I’m a homebody now. When they start school full-time, somebody’s got to drive them there. I didn’t have a dad — he wasn’t around. Being a father is very important to me. I want to make sure I leave my imprint with them.

At the Garden, they raised a banner to commemorate your 100th show. What are the odds we’ll see one for your 200th?

Don’t bet the farm. I’m still exhausted from the other night, which didn’t used to happen. I don’t think I’ll have the physical wherewithal to do it five years from now. And if I can’t do it as well as I want to, I’ll take myself out of the lineup. I love the game too much to not play it well.

So if you want to see the show, see it soon.

You can say that, but I’m not going to. I mean, these guys who do farewell tours — it’s funny, the farewell tour goes on for 10 years. The Who has had, what, like 20 farewell tours? I keep getting asked, “What’s the secret of your longevity?” I say, “I haven’t died.”

That’s good advice: Stay alive.

Yeah, don’t die. It worked for me.
