It's hard to tell if Paul was just suffering from winter time voice or if he was a bit emotional during part of his performance. He must be under an enormous strain with Iamaphoney having Mal's briefcase and all. Seriously, the lyrics to "Hey Jude" were especially poignant under his current circumstances. I dare say it could bring a tear to the eye. Speaking of eyes, I think there was a nice replica of the McCartney Eye on the stage. Enjoy the 3-Part video if you didn't get a chance to see it.
