Lloyd Bishop/NBCAt age 66, Billy Joel is about to become a father for the second time: he and girlfriend Alexis Roderick are expecting their first baby together late this summer. But the Piano Man tells Newsday he doesn’t plan to slow down and become a stay-at-home dad.

Billy, who’ll set a record on Wednesday when he plays his 65th show at New York’s Madison Square Garden, say he’ll continue his once-a-month residency at the legendary venue for the forseeable future. As he tells Newsday, “I’m planning on staying as long as the tickets sell.”

Asked how the baby might affect, Billy says, “This is who I am. Even when I have a baby, this is my job. It’s not like I’ll be on tour away from my child for any significant amount of time. It’s once a week and I come right home. Or if I go far away, I take her with me. Babies are pretty portable.”

Talking about his residency — and the record-setting 65th show that will allow him to pass his frenemy Elton John as the artist with the most performances at the arena — Billy says, “I’m not doing it to break records. I’m doing it because that’s what I do. I think if you hang around long enough, all this nice stuff happens to you…I just stayed around. I hung in when a lot of people might have hung it up.”

But most of all, Billy’s doing it because he’s having fun — and so are the fans. “The audience is having such a blast,” he says. “I look out there and think, ‘These people are really happy.’ I look around and we’re the ones making them happy? Well, we’re having a blast onstage.”

Once Billy breaks the record, he’ll be the only artist with his name on two banners in the rafters of Madison Square Garden. He already has one marking the record he set for most consecutive concerts at the Garden, which is currently 18, but which increases with every show he does. He’ll have special guests joining him onstage on Wednesday as well, Newsday reports.

“It’s a little strange to be what appears to be peaking at this age, when this should be the downhill slope,” Billy points out. “It feels like we’re cresting here.”

He adds, “There’s something very gratifying about it happening at this age. I never thought I’d still be doing it at this age. This is a kid’s job. I started out as a teenager and I’m still doing the same job that I did as a teenager. It kind of allows you to still be a kid in a way. It probably slows your maturity a great deal. It’s the fountain of youth.”
