Half of the city turned out this weekend to celebrate what’s great about Boston — its people.

On sunny or snowy days, Bostonians will help you out. The Tartan Army from Scotland and Norwegian soccer fans witnessed that last week.

This time, the surprise was all local.

“I’m the luckiest guy in the world,” said George Regan, as he gazed at nearly 300 people who showed up for the christening of his son, George Kenneth Regan IV.

“Teach number four to be a really wonderful person and he’ll teach it to number five,” said former Gov. Charlie Baker, who said that’s the secret to life. Baker himself is the fourth Charlie, with a son the fifth. We all stand on those who came before us, the former governor added.

Work will come around soon enough, but Saturday was a celebration that started at St. Gregory Parish in Dorchester and finished with a reception at Davio’s in the Seaport.

Regan, founder and CEO of the Regan Communications Group, welcomed everyone alongside his wife, Elizabeth, and their new baby boy.

Former Mayor Ray Flynn said it best: Reagan has “stood up for people who needed you.”

There’s not enough ink in this paper to chronicle how connections keep Boston thriving. That’s the space where Regan’s PR firm operates. There are plenty of other similar agencies; it’s just that George Regan has been at the helm of his group since he left former Mayor Kevin White’s office.

Maybe that’s what makes dealing with him so rewarding. Kevin White loved Boston, and that rubbed off on everyone who worked for him.

Former police commissioners Bill Bratton and William “Willie” Gross both spoke as did UMass President Marty Meehan, Denella J. Clark, president and CEO of Boston Arts Academy Foundation, Steve DiFillippo, Davio’s owner, and more.

Former Herald editor Ken Chandler, newly reelected Teamsters President Sean O’Brien, and car magnate Herb Chambers were some of the notables in the crowd.

“Elizabeth and I are honored to welcome our miracle child into the faith alongside the remarkable circle of friends, mentors, and partners who have stood with us through every chapter,” said Regan, who was just recently sick.

But, like Boston, you can’t keep a good man down.
