Yeah! Cool! I had no idea how to react when I saw Macca in concert in London in 2010. The whole thing was a blur. But luckily I was able to buy a bootleg DVD online of that concert, a lot of it was pro-shot. It's not fantastic quality but at last it give me a frame of reference as far as my memory goes. Time just seems to stop for 3 hours, I was literally in la-la land, like yourself!
