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, January 20.

He said: "In actual fact I am seeing the guy tomorrow, funnily enough, because there is something they want me to do.

"I'm not sure what they want me to do, I think they'll tend to dictate it rather than me. I might be doing something in the Olympics. I won't know until tomorrow."

The opening and closing ceremonies will be directed by Danny Boyle, the man behind Trainspotting and Slumdog Millionaire and is rumored to include music by Elgar and a performance from Sir Paul McCartney.

The Government recently increased the budgets for the opening and closing ceremonies of the Olympic and Paralympic Games by an extra Ј41m.
