Ringo Starr admitted he still refuses to sign autographs as he was joined by dozens of fans in Hollywood to celebrate his 76th birthday.
The former Beatles drummer staged an open concert outside the Capitol Records Building, as he urged people around the world to say "peace and love" at midday.
Ringo said he had no plans to reverse his decision to stop giving autographs because of concerns that signed items were being sold for profit.
He told the Press Association: "I don't autograph. All autographs are on stuff that I've (done). One of my paintings or something I'm involved with and it goes to charity.
"It doesn't just go out there for other people to sell."
Ringo posted a video message on his website in 2008 saying he would no longer sign memorabilia and that fan mail would be thrown away. He later explained his decision was prompted by people selling signed items on eBay.
Ringo was joined on his birthday by comedians Howie Mandel and Richard Lewis and former Eurythmics musician Dave Stewart, who performed The Beatles' song With A Little Help From My Friends. Ringo then took to the stage with Dave to sing his 1975 hit The No No Song.
After leading chants of "peace and love", Starr threw white rubber bands marked with his trademark phrase to the crowd before cutting a huge birthday cake.
Explaining why he promoted the message of peace and love, Ringo told the Press Association: "It's in my heart. The sixties - it started then as far as I know.
"It's important that the other side of the violence tale is peace and love and maybe they'll be more peace and love as the years go on."
Last week Ringo praised the UK's decision to leave the European Union, saying Brexit will allow the country to get back on its "own feet".
The musician, who lives in Los Angeles, said he was "huge fan" of the EU when it started but it had failed to turn into a "love fest".
""I think (it's) good," Ringo said of the referendum result. "Get back on our own feet.
"I was a huge fan when (the EU) started. I've lived all over Europe so I thought 'how great'. But it never really got together, I didn't think.
"Maybe in a business way it got together but everyone kept their own flags ... it didn't really turn into a love fest."
