Paul “screwed” up.

Paul McCartney shed some light on his shaky performance at last summer’s Olympic Opening Ceremony in London.

McCartney explained, “We were live, everyone was there, the world was ready and this bloody great bell goes off. And I forget I’ve gotta wait for it, so I go ‘Hey Jude .  .  .’ and someone presses the playback. So there’s me on the backing track, and actual me; two of us singing. . . The drummer wouldn’t look at me because he was in hysterics and I was thinking, ‘What have I done?’ There was no stopping, it was the Olympics.”
