As he prepares to perform at the Summer Olympics opening ceremony on Friday (July 27) in London, Paul McCartney is offering his two cents about Great Britain's soccer team. McCartney is unhappy that British soccer icon David Beckham was left off the team, telling ShortList that "I would've thought Beckham would be first choice because of his huge contribution to getting the Olympics. But some idiot decided otherwise. I feel a bit sorry for the three over-23s because we're going to be looking at them and saying, 'That should've been Beckham.' It would've been great for (Beckham) to lead out our British football team. But some person somewhere said, 'So-and-so's playing better.' Like it matters." The person, or idiot, in question is British soccer manager Stuart Pearce. Olympic rules state that players on national teams are to be 23 years old or younger, but each 18-player squad is allowed to add three "wildcards" who are older and Pearce chose three others rather than Beckham. Beckham was integral to London's successful bid for the 2012 games. McCartney is expected to both open and close the opening ceremony at Olympic Stadium. A soundtrack album from the event will be available digitally shortly after its conclusion.
