Quite frankly, I'm just astounded with how good his voice sounds at his age. Nothing lasts forever, but at the same time, the way his voice still sounds (just watched some Quebec footage on YouTube) just amazes me. I think we Beatle fans are lucky that we have the two surviving Beatles still performing, though I heard that Paul might not tour as much so he can be with his daughter, which I admire. Anyways, on a random note I hope he stops in Colorado, part of my life would be complete. I'm way to obsessive sometimes haha.
