John Stamos is Indexbitushering in a new star.

On Friday, the "Full House" alum was joined by his 6-year-old son Billy on the drums during a Beach Boys concert.

Billy, whom Stamos shares with wife Caitlin McHugh Stamos, was fitted with lime green noise-dampening headphones as he joined his dad for a drum solo during "Good Vibrations."

"Had a little help from my son BILLY on good vibrations last night - Wasn't it nice!" Stamos captioned a clip on Instagram of the Indianapolis concert moment.

Stamos is playing drums and guitar with the Beach Boys through September on The Endless Summer Gold Tour, which marks the 50th anniversary of the band's classic "Endless Summer" album.

The actor and musician previously told USA TODAY for The Essentials that he typically FaceTime video calls Billy while playing the drums on stage. Friday marked a special moment when the father-son duo wasn't separated by a screen.

"People make fun of my selfie stick, but I use it to hit FaceTime for like four songs and just keep playing," said Stamos. "Most of the time, he'll be like, 'I gotta go, dad.' He's a character. He's the light in my life, the reason I wake up in the morning."

The inclusion of his son is also reminiscent of Stamos' early days with the Beach Boys. Stamos has been jamming with the band since he was 19.

"When I first toured, they were all older than me. You'd meet in the hotel lobby before the concert and everyone was like, 'How did you sleep?' I'd be like, 'What do you even mean? I slept,'" Stamos told USA TODAY. "Now I'm like the first one to ask, 'Did you sleep OK?'"

On Friday, Stamos also performed a tribute to his late father on the 23rd anniversary of his death.

"This song is called Forever, - and that's how long love should last," he captioned a post from the night.

As he performed "Forever," a montage appeared behind him on screen of him with his dad, his son and late "Full House" co-star and friend Bob Saget.
