A lot has changed sinceJohn Stamoshosted PBS’ Capitol Fourth Concert in Washington D.C. last year. Although he was once again tapped to host, this year he came as a married man toCaitlin McHugh— and a first-time father.

TheFull Housestar, 54, made sure to give a shout out to his nearly 3-month-old son William “Billy” Christopher during the holiday show.

“This is Billy’s first Fourth,” he said. “Since we’re all here together at the nation’s capital, I think this is the perfect setting for me to pass on the lessons and love for this great nation that my grandfather passed on to my father and my father passed on to me. My son, for over two centuries America has given us an opportunity to be part of its great legacy.”

Billy even made the trip to D.C. with his dad, as the actor revealed in an Instagram post on Tuesday.

“Looks like we got a stowaway.#BillyinDC,” Stamos captioned a photo of his son laying in a guitar case.

In addition to taking on hosting duties, Stamos once again jammed out with his good friends The Beach Boys — just like he first did in amemorable episode ofFull House.

“What do you go to when you feel uneasy or anxious, you go to what makes you feel good and safe,” Stamos toldUSA Today.“That’s whatFull Houseis. That’s what The Beach Boys is to me. I think that’s what this concert is, too. People at home can turn it on and go, ‘We’re not as fractured as it may seem. We can still come to the nation’s capitol and play music and celebrate being American.’ ”

The future of the country has become even more vital to Stamos since becoming a dad.

“Everything seems very fragile. You want the world to be the best place it can be for him,” he told the outlet. “I mean, I always wanted the best for our world and our country, but now even more so.”

Two months into parenthood, Stamos revealed to PEOPLE how he’s been adapting to the diapers and tears — the latter of which he admits haven’t only been coming from his newborn.

He added, “I thought it was beyond me to have a kid and a great wife, but it’s given me a reason to live. Life is in session now.”
