When asked about the subject in June, McCartney said he would love to perform, but had not yet been approached by organizers. This time around he told Access Hollywood, "I hear there's a rumour that I might be involved. I've not actually heard anything [specific] about it yet ... but they are now planning the music."  Things are looking good for Beatles fans, as The Sun also reports that Danny Boyle and the organizers have expressed a strong desire for a performance by Paul, Ringo Starr, and even the offspring of George Harrison and John Lennon, all together now!
Coldplay, the Spice Girls, and Girls Aloud are the other groups rumored to perform at the Opening Ceremony, but let's get real, if you're attempting to show off the best that Britain has to offer, nothing even compares to the mighty Beatles. It would be more appropriate to spin an old Beatles record on a crummy sound system than hand over the stage to the Spice Girls. Beckham's appearance at the handover ceremony in Beijing made sense, but his wife and her girls performing would be an abomination.
