Sir Paul McCartney is in talks to play a part in the 2012 Olympics and says he "could easily" be involved in the Diamond Jubilee too.
The former Beatle, who performed at the party in Buckingham Palace for the Golden Jubilee in 2002, said he was going to a meeting about the Games on Friday.
"I might be doing something in the Olympics. I won't know until tomorrow."
Sir Paul, who was speaking at a promotional event in London for his new album Kisses On The Bottom, said he was a "big fan of the Queen".
He said: "I think she's great and I think she does a great job and people say 'ugh, the monarchy and all that' but what are you going to get in return?
"You'll get like, David Cameron? I mean much as we may love him I'm not sure I want him to represent the whole of Britain. Anyway, so if I get asked I could easily do it."
