It’s been a while since his Teen Beat pinup days, but Jordan Knight still elicits decibel-defying squeals from female fans. At least, that was the case when we caught up with the surprisingly still-swoon-worthy singer when he performed at the Estate during Dancing for Hope, a fundraiser for St. Mary’s Center for Women and Children. Next month, he leaves for a tour of Europe, Asia, and Australia with NKOTBSB, the New Kids on the Block and Backstreet Boys über-group — but not before a final stop on his solo Live and Unfinished Tour, which will hit Showcase Live (23 Patriot Place, Foxborough, 508.543.0609) on Sunday, April 1. Expect songs from his most recent album, Unfinished, plus the requisite dose of oldies. For tickets ($35), visit ticketweb.com.

How’d you get involved with the St. Mary’s event?
My wife is on the board. It’s close to our heart because we both grew up in Dorchester. St. Mary’s used to be St. Margaret’s Hospital. . . . I’d go there when I was little with Donnie [Wahlberg]. His mom worked there, and we’d go to get lunch money or money for the corner store or subway. My wife asked me to perform last year, and I told her, “No, I really have no repertoire right now.” Now I’m on the road doing my thing, so she told me this year I have no excuse. I said, “Well, who’s going to pay for the sound system and everything?” She said, “You are! ‘Cause it’s for charity! So get your butt up on stage and sing!” “Okay, okay. I got you!” [Laughs] But it’s a great cause. We grew up in Dorchester and know how hard it can be. Some people have it rough in life, and all they need is a helping hand.
