Sir Paul McCartney paid tribute to the other "three boys" in the Beatles as he unveiled his own star on the Hollywood Walk of Fame.

The rocker was introduced to a crowd of fans in Los Angeles by Neil Young at a ceremony in front of the Capitol Records building.

Sir Paul said: "Way back in history, in Liverpool when we were kids and we were listening to Buddy Holly and all the rock 'n' roll greats, I would have never thought that the day would come when I'd be getting a star on the Hollywood Walk of Fame.

"That was like an impossible thing to happen but here we are today and it's happening."

Sir Paul, who was joined at the ceremony by his new wife Nancy and son James, said bandmate Ringo Starr would have joined them but he was "a little under the weather".

He said: "I couldn't have done it certainly without three boys so I want to say thanks to those guys, John, George and Ringo."

It was announced earlier this week that Sir Paul will headline a spectacular musical tribute to the Queen to mark her Diamond Jubilee.

The former Beatle will be among a concert line-up that will feature artists from across the 60 years of the Queen's reign playing in front of Buckingham Palace in June.
