I think we'll see the Beatles reunion happen first...
Peter is a different guitarist to the one he was then, much less a showy player, in my mind more like JJ Cale's understated style of guitar playing. Some people would expect the old Peter. I remember a review of a Jerry Lee Lewis gig in the NME music paper years ago. He'd just had a stomach operation, and the reviewer concluded that it was a wise move he hadn't tried to stand on his piano as there'd be nothing sadder than seeing a rock legend do that and have his guts fall out all over the place!
In spite of what people might want, sometimes you've just got to not do something...
