"Our goal was to get him at the Ryman this weekend. He wanted it," Stamos said. "I've been spending a lot of time with him, you know, quiet time. We listen to music... doo wop, he loves doo wop."

"And I said, 'You have to tell me, do you really think you can do these weekend shows?'" He said, "Yes, and I really want to."

Stamos added: "Everyone told him — the doctors, his family — but this is what he wanted to do. He fulfilled all my dreams and all my wishes. So I had to fulfill his wish and we made sure he did. I got there and I did a good job."

SRF presented John Stamos with the Bob Saget Legacy Award, recognizing his steadfast support of scleroderma research and his commitment to following in Bob's footsteps with regard to scleroderma and raising funds for a cure for scleroderma.

Brian Love, son of Stamos and Love, spoke before the screening.

"One thing about him is that he's tough and he's steadfast and he didn't want to lose Ryman. I mean, look at this place for a good reason. So we're happy. We're going to be positive. We sing together, but I still remember something he said to me as a kid and it stuck with me. 'Dad, why are you doing so many shows?'" Bryan said, via Variety . I mean, we're talking about a guy who was doing over 100 concerts a year well into his 80s.

He added: "It's incredible, right? So he said to me, 'Well, if you don't do as many concerts, you're not going to see as many cities, and that means less people can hear the amazing Beach Boys in person.' We have to live in the moment."

"All we have is tonight, really, and I think it's going to be very, very special," Stamos said afterward. Mike, he insisted on being here... he's done over 7,000 live shows. And tonight it will be exactly 7422. I think that's where we are. He's counting... I love you guys, and have a great night, and God bless you all."

This media reported that after the curtains opened, Eshq was already sitting on the stage.

He sang in his chair with his bandmates and did not perform his original vocals.

During the performance, the Beach Boys legend addressed his health concerns, saying, “Obviously, I've been dealing with some health issues for a long time. But I didn't want to be with you in Ryman."

Variety reported that at the end of the show, Bryan and Stamos helped make love and Queen performed We Are The Champions.

In her social media post, Stamos acknowledged that Love is "a fighter" and despite "doctors, family and friends urging her to focus on her health, she insists on being on stage."

"He says he needs his band, the audience, his friends and the drummer around him to lift him up," Stamos wrote. I played with Mike for 41 years. "I never imagined how much it would affect me to see someone larger than life come face to face with something so human and so fragile."

The Beach Boys are touring in support of the 60th anniversary of their groundbreaking 11th studio album, Pet Sounds.

Stamos noted that “the Mike Love we see tonight may not be exactly the Mike we've always known. But he's still the Mikey we love."

His lyrics, optimism, unforgettable hooks and more than 7,000 concerts have brought him joy. "What he has given me personally is immeasurable," Stamos wrote.

He taught me how to entertain, stage, connect with an audience and make people feel something. "I take these lessons everywhere," Stamos said. He has made me a better musician, entertainer and man.

"This life with Mike and the Beach Boys has become part of who I am. I feel like I'm a steward of this wonderful music and passing it on to new generations."

Stamos wanted to be “fully present,” performing with Love at the Ryman over the weekend, and “hear every familiar harmony, joke, and joy. Feel the first stroke of the chord and watch age, disease and time disappear. "Just a few people making music together."

"Perhaps the hardest part of loving someone is getting so used to being a miracle that you forget it's a miracle at all," she wrote.

"Tonight, I will not forget," Stamos wrote. "I want to cherish every second without feeling like those seconds are wasted. That's what I give him."
